So than it would stand to reason that you have some engine settings that are causing the crash?
Before migrating, had anyone suggested deleting stuff in your /saved folder yet?
If not, you could check what can be safely deleted and try to re-open, re-build shaders on the old project.
It’s probably the same result as what you did by migrating btw.
Personally would still be interested in knowing why the engine was crashing out over this.
You should give .27 preview a try with a copy of the project too.
