Edit: accidentally was running two different versions. Got rid of the old one.

Error for updated version: Protontricks was closed due to the following error:

Won't let me run commands in terminal with the flakpak version: ~$ protontricks --vv --gui Command 'protontricks' not found, but can be installed with: sudo apt install protontricks

If it do sudo apt install I get the ubuntu database version which is older but allows me to run it in terminal

Can you try running the following command in a terminal emulator:

flatpak run com.github.Matoking.protontricks -vv --gui

It should print additional log messages that Protontricks is not able to capture into the error dialog. Can you copy the full output to gist.github.com and post it here?

Same as the previous issue report, the bwrap launcher crashed, returncode: 1 message means the bwrap launcher is crashing, and the error message for that is not something Protontricks cannot capture and display in the error dialog, requiring this workaround,

I got the same Issue and used the mentioned command. Here's the Log: https://gist.github.com/ShadyDemoness/46417666ee49d9b3d76f71a50cdee867

This feature requires Flatpak to be using a bubblewrap (bwrap) executable
that is not setuid root.

The non-setuid version of bubblewrap requires a kernel that allows
unprivileged users to create new user namespaces.

Same error in my environment

Same error in my environment

I run with the "--no-bwrap" flag with the command:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=protontricks com.github.Matoking.proton  
tricks --no-term --gui --no-bwrap

Launch via the terminal.

Thanks, --no-bwrap works
