I've tried running steam with the dedicated GPU option
What exactly are you running to choose the dedicated vs integrated GPU?
I also get the freezing issue without running with the dedicated GPU when I launch steam but found that launching directly to the steam settings window from the menu reduces the chances of freezing.
Hmmm, whenever this happens, it might be worth looking at the kernel logs, see if something crashes. You can check them with either
journalctl -k -xef or dmesg
Kernel: 5.15.0-82-generic
In general it's recommended to stay on newer kernels/mesa when using the open source GPU drivers, could be worthwhile trying to update that (think there's a PPA you can pull from)

Seems like you can try and debug the execution by running
switcherooctl launch *application*, which should (manually) do the same as when you right click and clickLaunch with dedicated GPU, because I think Mint is using switcheroo, same as Gnome is.But would then hopefully log some debug information for you in the terminal itself
