ERROR: ld.so: object '/home/peafield/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
But I'm not even sure what this points to now.
Can anyone help? Or is anyone going through something similar with a similar set up?
EDIT: The solution, as many of you suggested, was to just change distros. I'd heard good things about Fedora so I tried it and everything ran first time with no tweaking! Thank you everyone for the advice.
Weirdly I cannot toggle the steam overlay on it is greyed out but I believe it is off. And I have Compatability > For the use of... ticked and proton experimental selected.
