Just in case someone else finds this, there’s a bigger discussion about this issue in another thread:

I don’t know if this is going to help everyone but i was also having very frequent crashes whenever i would try and edit a camera animation in my scene which made it literally impossible to work. Whilst digging down the youtube rabbit hole of UE 5 optimisation, i came across this video which is nothing at all to do with the camera animation crash issue but linked in the description is his “optimised config file” for the project he made using nanite and PCG for level design. Since i was playing…

I have the exact same problem in 5.5.1 and sadly no solution.

EPIC have seemingly tracked down what this issue is about, and will push out a patch with 5.5.3. The issue is fixed at source since today apparently: Unreal Engine Issues and Bug Tracker (UE-234045)

Until the patch is out, building from source may be an option (if only I knew how to do that).
