I’m having the SAME ISSUE
After the new season update the session crash after 3,4,5 rounds.
We thougt it was related to player joining and exiting the session but we were completely fooled. We have been debugging for 3 straght days various versions, trying everything possibile also deleting the whole map and keeping just the logic but nothing works. This is getting really frustrating.
We tried also old versions of the map we played without problem in the previous season and they started to have that problem too.
Some additional info if useful per devs, we were crossplaying the map: 2PCs 1PS5
