Have a try on 4.24 with hulls - even .25.
Just a hunch here that they fu*ked the .27 release when they shouldn’t have.
Just make sure whatever you try is using PhysX and not Chaos.
This probably boils down to;
Chaos is sh*t and Epic is clueless.
But you know, its nice to confirm it before making blanket statements.
Now, supposing this is true, to get your old project loading right after you confirm chaos is the issue, all you have to do is build from source using PhysX.
Easier said than done for 5…
