PROTONTRICKS_STEAM_RUNTIME not set about protontricks HOT 2 OPEN

It seems that the Steam Runtime launcher is not starting up correctly, causing the later "Unable to connect to any of the specified bus names" error. The error here seems to be the culprit:

pressure-vessel-wrap[21671]: E: ':' and '\' in --filesystem argument not handled yet

One of the directories in your root contains a : character that Steam Runtime is not able to grok, causing it to crash.

If renaming or deleting the offending directory is not an option, you should be able to use --no-bwrap flag as a workaround, though that means Proton won't be run under Steam Runtime and you might run into other issues.

As a side note, the executables Protontricks creates under ~/.cache/protontricks/proton are not meant to be run directly, as they rely on various environment variables being set up during runtime. If you want to run them interactively, you can open a shell session using Protontricks so that the environment is correctly set up:

$ protontricks -c bash <appid>

from protontricks.

I pushed a change to master that should now check for successful bwrap-launcher and halt early if something goes wrong. This should make the culprit more obvious going forward, as it should now be the last error in the logs.
