My computer restarted with Steam open and upon relaunching it none of my games on a secondary internal SSD were recognized. The drive is Ext4 and the relevant line from fstab is
UUID=99d2c67d-cbd0-43b4-af73-fad5a79fcd08 /media/datastorage ext4 defaults 0 2
All of the Steam games are still on the hard drive, but Steam says "New steam library folder must be on a filesystem mounted with execute permissions" whenever I attempt to use the app to re-add the library.
I have tried several other fstab options recommended on this platform already. My user has full read-write permissions for this folder and drive. All of my Steam library folders already have "steamapps" in all lowercase. I noticed some other users have had issues with Windows dual boot, but I do not have this and only have one Windows virtual machine set up (but not running nor on the secondary SSD).
My system information is: Pop!-OS 20.10 (Ubuntu based) on a Dell Precision 5550 with an i7-10850H and an NVIDIA Quadro T1000
Let me know if there's anything else I should include! Thanks for the help!
