Steam launch fails 2023
I an unsure when this issue began to occur, but Steam does not launch using Box64/Box86.
This issue was reported by a Pi-Apps user who used Pi-Apps to install Steam. I have confirmed the issue: Steam does not launch successfully.

On first run with no pre-existing config, a number of dialogs appear to download and extract Steam. This seems to succeed. But when running Steam again later, it quickly exits with this output:
(Note: /usr/local/bin/steam is a pi-apps custom wrapper script to launch steam)
```

This output is unhelpful, so I ran steam manually using these commands:
```
export STEAMOS=1
export STEAM_RUNTIME=1
export DBUS_FATAL_WARNINGS=0
BOX64_LOG=2 BOX86_LOG=2 BOX64_EMULATED_LIBS=libmpg123.so.0 /usr/lib/steam/bin_steam.sh -no-cef-sandbox steam://open/minigameslist
```
The debug output from this is too long to capture in the terminal, but the ending part seems the most interesting:

Hoping someone here can look into this and see what can be done to get Steam working again.
