I’ll end it here.
If you are curious I’d check out the following link and see what version of mesa you are running vs the latest. Maybe you can find more info or other experiences from users on that specific version.

If you want to explore a newer kernel: https://ubuntuhandbook.org/index.php/2023/08/install-latest-kernel-new-repository/amp/
Finally, I’m curious if you boot using USB into a live distro like Nobara, if you can manage to test the game. Or even actually install Nobara to a spare USB drive drive and test the game.
Maybe someone else can chime in, but that’s about all I can think of. If you want to find a root cause, you have to run through and find what’s not the issue.
I’m not so sure it is either, but since you’re on kubuntu you don’t easily have access to newer mesa/kernel to test software.
Troubleshooting is not about finding the issue right away, it’s about eliminating by going through all of it and trying it to narrow it down.
Have you tried a distro with a bit more recent packages? If it also crashes then we know it’s more likely something with your hardware.
This is just a guess, but I imagine kubuntu probably has a slightly dated kernel / mesa versions. My understanding is that As much as we wouldn’t like it to be the case, there’s still issues with AMD. It’s not totally perfect and Improvements and fixes are being added to the kernel and mesa packages all the time.
Maybe someone on AMD can confirm?
I own the game and did not experience a crash when playing through it on my nvidia system last year.

Add this as a Steam launch option for the game:`PROTON_LOG=1 %command%`
How?
1. Right-click on the game title under the Library in Steam and select Properties.
2. Under the General tab click the Set launch options... button.
3. Enter the above code in.
Logs will be saved to $HOME/steam-$STEAM\_APP\_ID.log, overwriting any previous log with that name.
If it’s happening on your desktop but not the steamdeck, my first assumption would be an issue with your desktop software/hardware.
Might want to check OS logs at the same time of the crash as well.

I don’t see anyone else mention crashing: https://www.protondb.com/app/201810?device=pc
FYI
Since AMD GFX works out of the box and steam is preinstalled in some live distro’s… simply mounting the hard drive with the game and then adding it to steam will work. Allows you to add the game ( steamlibrary) without having to download. Just a thought.
