Meta app suddenly wouldn't start, uninstalled and then will not install new version 1.86?

[stu.burling]

So i went to fire up Meta Quest app this morning (was working fine with my Quest Pro yesterday).

After 4 or 5 attempts at starting with headset unplugged and plugged.  Still no luck.

Firewall and Anti-virus both completely shut down.

Updated nVidia drivers.

On a couple of occasions the setup app seemed to be about to start but then the black square in the middle of the desktop just disappeared.

So i uninstalled and deleted ALL oculus and oculus related folders/files on my PC incl. in Users\XXX\AppData\Local, LocalLow and Roaming.

Also deleted all registry entries related to oculus software with Revo Uninstaller.

Several restarts/shutdowns etc. Still oculussetup.exe won't start or crashes after 3-4 seconds.

Searched online.

Tried ALL the steps on this page:

https://smartglasseshub.com/oculus-software-not-installing/

Unplugged all devices except keyboard and mouse.

Nothing works?

See log file text below.

Any help appreciated.

Not sure what your problem is mate.  My QPro continues to work great with both Link and Air Link.  I'm sorry I can't help by looking at parts of your log file.  I suggest you start a ticket with meta support and include your log files to see if they can identify your problem.  Good luck mate and cheers.
