It is important to note that because I'm using debian 12 steam was downloaded using flatpak
I have joined the csgo_legacy beta participation for Counter Strike 2 in hopes that I can run CSGO with better performance than counter strike 2. Upon clicking the play button Counter Strike 2 launches without giving an option to lauch the beta. I am unsure of why this is and I can't find any info about this problem (this is not the main problem though). Adding the game to steam as a Non-Steam game tries to launch it but fails. Running csgo_linux64 in the terminal gives me the error ./csgo_linux64: error while loading shared libraries: libtcmalloc_minimal.so.0: cannot open shared object file: No such file or directory while running csgo.sh tells me CS:GO was not launched within the Steam for Linux scout runtime environment. Issue #2563 tells me how to launch CSGO with the steam runtime but that gives me the error Failed to connect with local Steam Client process! my guess is that this is due to flatpak storing the steam files in a different directory. Searching up how to fix the first error tells me that I just need to install libtcmalloc-minimal4, with this installed though I still get the same error and no change in logs. Another issue told me I needed to update my GNOME desktop, I updated to 44.5 (the lastest debain will alow in the unstable repos) and this fixed nothing. A number of other things were tried but nothing was fixed I have validated all the files many times and each time is a pass. This is my last try at fixing, thanks for your time and help :).

Steps for reproducing this issue:

1. On debian 12 launch steam (downloaded using flatfak).
2. Download the csgo_legacy beta for Counter Strike 2
3. Click play, counter strike 2 will launch and give no option to launch the beta
4. In the terminal run ./csgo_linux64 and see the error.

Let me know if anything needs to be added please tell.
