Steam version not launching at all on Linux (Ubuntu 22.04)

[onurubu]

I am trying to run the game on Steam using the native Linux version. When I click play the game does not launch whatsoever, there is not even a window that pops up. The play button changes to "Stop" and then immediately changes back to "Play". I have tried reinstalling the game multiple times on Steam and have also tried to verify the integrity of the game files.
I have heard others have had success in running the proton version of the game instead of the native Linux version, however if possible I would like to figure out what is causing the problem and solve it.
Due to the nature of the game not launching whatsoever, it does not even generate a log file.
I have attempted to run the game through the terminal as some people have suggested in Steam discussions but this has not worked either.

So for the terminal case:

1) what did you download exactly from where?
2) where did you save it?
3) how did you start it (starting from which directory)
4) what happened on screen - what was output?

Try running it with PROTON_LOG=1 to force Proton and generate logs.

You can launch the game manually from the terminal (./t-engine) to check for missing libraries,Retro Bowl College and install required SDL2 dependencies (libsdl2, libsdl2-image, libsdl2-mixer, libsdl2-ttf).

I thought ToME has a native Linux client, and so don't need to use Proton, CMIIW?
