@Flak Hi, could you help me understand what actions/info would be needed to involve Epic to troublshoot this critical issue that prevents dev work completely for the affected people?
Some more observations:
If I sync to a Revision Control’s OLD snapshot from Mar 24 (before 34.20 update) and don’t change it in Editor, I can start the Edit Session from UEFN
… but if I do any changes on top of that old snapshot, the same happens: Can’t start the Edit Session
If I create a Private Version from that OLD snapshot and set it as the Playtest build, I can start it fine from Lobby on all platforms I tried: PC, PS5, Xbox One
… but if I create a Private Version from the LATEST snapshot (done after 34.20 update), the game’s start status in Lobby gets stuck at “UPDATING… 100%” on all platforms (PC, PS5, Xbox One)
I was browsing throw the logs and it just keeps sending LogDownloadOnDemandGameplay: Verbose: [3d2c] Failed To create Download On Demand Project. Link entry was deemed invalid : with different ids.
I also tested with a mobile session and it didn’t crash but it never loaded
Everyone - as an update, the team is checking into all of the logs and is investigating. I’ll let you know if we need anything else. Thanks so much for the detailed reports and for getting us logs.
Hi, my team was having the same issue in one of the projects, and we had to go back to previous versions until we realized it was a custom device instance. Once we identified it, we just had to delete and re-add the device on the map, and the game opened without any issues.
Quick check after 34.21 update: It didn’t fix the problem in my case (not that I would have seen any claim that it would fix this issue). FN still crashes when I start my large project’s Edit Session from UEFN.
(Good find by Raikiri125, but unfortunately didn’t help in my case. I took an old pre-34.20 snapshot, didn’t add any custom Verse devices, but FN still crashes if I make the smallest change I can think of by slightly moving an existing prop)
