[BUG][LINUX] - Can't select steam directory + unable to launch r2modman without sudo

[tasnimtamim]

UPDATE: I found steam.sh on /home/.steam/steam/steam.sh
Trying to open Outward Definitive Edition. Set the location properly
But I'm now getting this error

Describe the bug
A clear and concise description of what the bug is.

1. Cannot select steam binary. The file selector I assume only accepts .sh files so pointing to /root/usr/bin/ it doesn't find steam file. Picking /usr/lib/steam/bin_steam.sh says steam executable was not selected.
2. I cannot launch r2modmanplus normally. It would open the window and close again. Terminal output is this:
   /usr/bin/xdg-mime: line 885: qtpaths: command not found starting server on /tmp/app.r2mm starting TLS server false starting server as Unix || Windows Socket [83108:1002/193900.942379:FATAL:gpu_data_manager_impl_private.cc(445)] GPU process isn't usable. Goodbye.
   Launching using sudo and --no-sandbox works just fine.
