Hey,
i have a litle problem. My created game function perfect in the Editor. And very good after the build. But on other PCs, its crashing when the play enters a triggerbox an open a level by name.

this is the Error:
Assertion failed: (Index >= 0) & (Index < ArrayNum)
[File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 763]
Array index out of bounds: 0 from an array of size 0

I have an identical problem but was caused when I removed material entries from GeometryCollection, I think :s
Did you find a solution?

Similar for me too.

i have the same issue too. it appears when i try to set a parameter of a material using blueprints(using a tick function ) and end the PIE session. it does not occur 100% but eventually will crash the editor.
any ideas of how to fix ?
