Steam games not launching

i have downloaded fall guys and when i try to launch the game, the steam comes for a second and goes. the play button reappears on the game title. i have enabled steam play with proton experiment and also enabled it for other titles and also for falls guys compability i have enabled to force run in with proton experiment, but still it is not launching and same goes for the other games i have tried. please help me, i installed zorin bcoz it supports steam.

Are u installing steam library files on any mounted secondary hard disk?
Because I had the same problem when I did that but if u keep your steam files on the drive you installed your Zorin os then that failure to load the file system will not happen.

yes because my primary hard disk has only 128gb.
edit: i tried installing on primary disk but same issue.

PC specs?
