I have a big Premiere project for a video course with about 400 sequences (will be around 8 hours of a final cut, 40 hours of raw material), many morph cuts and lots (!) of sudden crashes (with Adobe Crash Reporter, no system errors).

The very helpful German Adobe support went with me through all the usual stuff (emptying caches, different admin user, stronger hardware, performance tweaks etc.), but nothing helped.

It is a team project, but is also crashes as local project and with other users. Hardware seems not to be the issue since it crashes on a top notch M1 MacBooks Pro as well as on a weak Windows laptop with the minimal hardware requirements.

Shorter timelines seem to crash less than bigger ones, but that is the only pattern we can make out so far.

All materials are 1080p25 ProRes Proxy and 24 bit 48 kHz Wave. All timelines and material have the same settings.

The sequences do not have very complicated content. It is usually one video stream and two audio streams.

We tried to always wait for the analysis of morph cuts and also render them, but that did not make a difference.

We also split the project in parts, but that makes no difference (makes it just more complicated).

There are also days when nothing happens and times when it does not stop crashing every two minutes, working on the same timeline.

I always sent the crash reports, but did not hear back so far. I saved two DMP reports.

There are no effects applied, no CC, some titles, but problems were there before the titles.

Besides the morph cuts, this is material-wise like a bigger film project.
