When copying a large number of files, the 561-line set of .\Engine\Source\Runtime\Engine\Private\TextureCompiler.cpp in the DirectoryWatcher module in UE5.1: TexturesToProcess is accessed out of bounds during subsequent use, causing UE to crash.
Hey there @_95! Welcome back to the community! Sounds like this could be related to the scale of the copy, is this reproducible at smaller scales?
Yes, there is no problem when there are not many resources. When the resources exceed 100, problems start to occur.
Generally when resources are overtaxed errors are more prone to occur, especially in situations where there are built in timeouts as a failsafe. There may not be a possible fix for this aside from smaller copy chunks. To be on the safe side, if this can be replicated when resources aren’t maxed out, we would definitely like a report!
