I only had problems with games on Steam when I tried to install the latest Ubuntu distro, Ubuntu 24.04 LTS (probably due to lack of drivers.). Other than that, I have no problems, almost everything runs very well. I now use Pop OS as well and have no major problems. Regarding Proton, in some games, especially online games, it is necessary to add Proton GE, an alternative and unofficial Proton.
But specifically in this case of Voices of the Void (maybe because is a non-steam game? Idk), the same error persisted as with C++. What I did was install C++ from Wine, but, as I reported above, it did not work.
