Dynamic Link between Premiere and After Effects is a complete failure
Even in 2020 Dynamic link is far too unstable to even consider using in a professional workflow.
The ratio or times I have tried to have simple text only comps from AE in a Premiere timeline for just one crash to make dynamic link between the two forever again unable in the project is 100%.
A single crash causes enough mayhem that the next two hours are spend searching in the void for solves.
Rename the Dynamic Link Server folder.
Delete all the linked comps. Import again.
It's never the same.
If you can even get the projects to open again.
"Dynamic Link is used daily in demanding professional workflows."
Every company I've worked at refused to use it!
I'm also curious if you've considered using the Motion Graphics templates workflow for your text titles. You can create editable packaged AE Projects (.morgts) and edit them right in Premiere without having to bounce back and forth. 99% of them are rendered by a Tiny Inception AE inside of Premiere Pro and are shareable across, slack, emails, servers, and CC Libraries.
Here are a few resources if you're curious about how to get started:

Dynamic Link is used daily in demanding professional workflows. Let's see whether we can get it to work, for you.
Do you have the current versions of both PPro and AE installed? Specifically, which folder are you deleting? Do you get any different (hopefully, better) behavior, when using the auto-saved versions of the projects, open during the crash?
Restarting your OS after a crash = great idea.
