PRmumble doesn't launch while joining server

[Estonian_Bus_Driver]

When I try to connect some server I get this random "PRlauncher{67802507..." text in left bottom corner of the screen. I have read that it means something that PRlauncher couldn't start mumble.

I have tried everything, running in compatibility modes, allow firewall and antivirus, launching mumble with game on or off, reinstalling PR etc. but nothing seems to work.

Does anyone know how to fix this problem?

1920 x 1080 (32 bit) @ 144 Hz change to 60 herz version and try again

project reality runs only in 60 Hz version

maybe lower graphic settings

How does this have anything to do with Mumble not launching?

Using 60Hz or lowering video settings doesn't make any difference

Anyone? I don't know what to do anymore
