Premiere Pro is hanging my system - 100% CPU usage when generating thumbnails in bin. Eventually it will go back down to normal usage, but if I try to do other things while this is populating it may cause my computer to BSOD. Last BSOD (this morning) was KERNELSECURITYCHECK_FAILURE
I should note that my system has 0 stability issues doing anything else except when using Premiere Pro.
This just started after the last update to Premiere Pro (15.0)-
This does not happen with 14.9
I am able to recreate the hanging and or crash by opening a folder and generating thumbnails.
This happens with 4K timelines, 1080 timelines and with 4K footage, and 1080 footage.

I've been having a huge issue ever since updating to Premiere 2021.

On my timeline when I extend a video clip by dragging the ends with the selection tool, the preview screen flashes on every frame. It looks like it is flashing back and forth between where the playhead is and the frames I am extending.
Here is a screen recording of that happening: https://www.youtube.com/watch?v=1lwbIh9zSzw

Every time I make any change or adjustment to any clip, text or basically anything on the timeline, the preview screen changes between aspect ratios, and low-res previews and then pops back to normal.
This happens Every time I even touch anything on the timeline.
This isn't an isolated glitch, either. It happens in every project I've started and opened.

I reset Premiere and trashed the preferences already. I have run out of options.

Has anyone else experienced this problem? Any help will be greatly appreciated as I can't even edit without near getting a seizure from the preview monitor flashing.

My system:

-2017 iMac 27"

-Latest OS

-4.2 GHz Quad-Core Intel Core i7

-64 GB 2400 MHz DDR4

-Radeon Pro 580 8 GB

Premiere Pro CC 15.2 running on 2020 Mac Mini with 8GB RAM - MacOS Big Sur 11.4

Memory leak starts immediately and skyrockets after any edit, making editing impossible after just minutes. What this means is I have to restart Premiere after nearly every edit. Massive hit to productivity.

You can see in the attached screen recording, at one point tonight Premiere maxed out the 8GB memory and then used upwards of 12GB of Swap Memory, which also negatively affects the lifespan of the non-replaceable SSD in this computer.

Fix this ASAP.

Linking to video since the screen recording was apparently too large to attach.

Since i updated premiere to the latest versions like 14.8 - 14.9 - 15.0 - 15.0

almost all this versions make me impossibile to edit projects after a while. I'm a Youtuber and i work every day to upload a video so i need a fast and responsive timeline for a project with a lot of cuts and nesting for what i'm doing. I work with Nvidia Shadowplay (.mp4) and OBS video files. Now to the bugs:

1- After a while when i start to cut and nesting some clips the timeline freezes forever the only way to get it to work is to press CTRL + S to save the project and then it starts to function for a while. This happens a lot, and with the last version 15.2, when the project as a lot of nesting involved, it will cause it to lag to the point that is impossibile to edit it!
It also make disappear some tools, mouse cursors like snaps magnetic clips, arrow ecc.

2- It seems that the audio in audition doesn't match the same levels in premiere pro, it's like is -2.db quieter in premiere pro than in audition
4100hz - waw audio file.

3- I don't know if this works better now, but i had a lot of problem when
i put hard limiter in all my (cutted) audio tracks. everything starts to lag and is impossibile to work with. Only solution is to nest every audio on the audio tracks and then apply the hard limiter or other audio effects. It seems that some audio effects, affects performance of the program.

My pc specs: AMD Ryzen 9 3900X 12-Core Processor 3.79 GHz 32 GB Ram Nvidia RTX 3080

Those are some of the hard bugs that i want to be fixed, thanks!

I'm trying to simply import a graphic into Premiere and put it on the timeline, and when I do, I can't see the playhead when I try to click anywhere on the timeline, and won't show the scrubbing of the video. When I remove the graphic from the timeline, everything's OK again. I tried with different graphics, different formats (JPG, PNG, PSD), all "normal" size graphics for HD for crying out loud, nothing crazy like 32000 pixels or anything - although your software should be able to handle anything in 2021. You've had the ability to import graphics for YEARS - HOW COULD YOU BREAK THIS?? I swear, if DaVinci Resolve could import vector graphics I'd be back in a heartbeat.

Premiere Pro made the render successfully once, but I rerun the same render a second time, then a third and it stops half way.

I checked my computer performance process, nothing wrong during the render. In the attachment, the two files are the exact same video rendered (I just added 30 seconds at the end of the second), but the second it slightly smaller (and shorter) than the first, though the explorer tells the duration is fine.
The second will stop reading at 29'39" which leads to nothing in the project.
No effect, no color grading, as you can see on the second attachment.
Actually, I can't make the render of my project, which is some kind of frustrating.
