PS5 Backports Only Work Once

[TechnicolorNX]

I have a PS5 running firmware version 9.60. I'm running VoidShell 3.0 and have it set to auto-load the latest version of BackPork.

I can install backported versions of games that require newer firmware (10.01 and up), and they will be detected and launch just fine. However if I close a game, the next time I launch it, I just get the error "Could not start game or app".
This happens with both raw dumps and games in .exfat format. Rebooting the console and re-injecting the Backpork payload do not fix it. I've tried completely deleting and re-copying games (including DLC and save data) and that does not work either. Backported games will always fail to start after the first launch.

Has anyone else encountered this? I can't find anything online that sounds remotely like my issue.

Edit: after further testing, this issue seems to affect all PS5 games, not just backports

Update: I've fixed the issue by switching from Voidshell to PS5 Payload Manager, and going back to etaHEN/Itemzflow. Some of the backports I have now freeze on a black screen, but I think it's a problem with those specific games. Everything else works fine now.
Not sure what was going on with Voidshell or why it suddenly stopped working. I'd been using it without issue for over a month.
