can't launch session [MissingArchiveFile] Failed to open zip archive

Summary

me and my team can’t launch a session anymore after our latest changes to our map, as soon as we click launch session shortly after we get this error

( “errorMessage”: “MODULE VALIDATION FAILED (job 6244a173-827c-4c43-994f-da9bcabd675f):\n[MissingArchiveFile] Failed to open zip archive C:/input/ProjectName-1.zip”)

and there is little to no info on how or why this is happening and how we can fix this,
we suspect it’s the amount of actors in our island and we have around 67k actors and we tried deleting some and then we we’re able to launch a session but this is not what we want to do,
and we can’t find any info about actor limit, and we have world partition setup correctly and we are really at a dead end
and we would love to have a answer to our question as to why we get this specific bug.

Steps to Reproduce

have more than 65k actors in your project with streaming enabled and have world partition set correctly

Expected Result

we expected to have the session launch normally but that is not the case, and we do not want to remove all our hard work!

Observed Result

65k actors results in the error code mentioned above and it does not tell us why it’s happening and we can’t figure out a solution

Platform(s)

pc windows 11

this is probably a coincidence but zip files used to have a limit of 65535 files

that was quite a long time ago though

would really appreciate it if this can be looked at

I have the same problem
