PTC V76 breaking sideloading?

Edit: I’m using Quest 3

Is it just me or is PTC v76 breaking apk installs?

I finally found a combo of settings and apks for my needs and decided to do a fresh install after a factory reset to wipe out all the previous stuff that’s no longer needed.

I was able to get sidequest installed and setup through the normal PC method but I’ve been having a lot of problems since. I’m not able to install any APKs on device standalone. Through PC sidequest I’ve installed amaze file manager, and lightning launcher but when i open an APK it asks for permissions and everything seems normal until I choose “install” from the toast, then nothing happens. After giving permissions subsequent attempts just do nothing. I’ve verified permissions are set in Lightning launcher android settings. I also can’t get the sidequest Quest app to open reliably, it’s just showing a black screen and times out. I’ve tried a couple reboots and even a fresh factory reset and still had the same issues.

Looks like things might be OK sideloading through desktop Sidequest but I only tested the above apps. I’ll continue doing the rest of my setup through tethered ADB but just curious if anyone else was experiencing similar issues.
