Games will not launch after enabling VNC

[Red_Trev]

Hi all,

I have a Rapberry pi 4b 8GB with offical power supply, running latest version of Retropie.

Everything was working fine, then I enabled VNC via the Raspberry Pi Config menu . I also Updated the tool to the latest version via the same menu.

Games will not launch for any emulator now. When I click the game, the screen goes dark, the grey box with emulator name appears, then screen goes dark & I am brought back to previous screen with the games list.

Also I cannot update any core packages as the pi cannot connect to github. The pi thinks its offline even though it is connected to my WiFi.

I have tried disabling VNC but the behavior is still the same as above. Turning the pi OFF/ON does not fix it either.

Is there anyway of rolling back the changes to what they were previously ? Or maybe VNC / Updater has a lock on a process that is preventing anything else from running ?

If its too much effort to fix I will wipe the SD card & go for a fresh install, assuming VNC / Updater is located on the SD card & not on some BIOS on the pi itself ?

All help is appreciated ! Thanks.

Seems to be an issue with the screen resolution, when I downgrade it the ROMs launch again ....

Will keep you updated on any fix, thanks .
