This is kind of only a patch fix to your problem, but as a fellow Linux user, if you are manually configuring wine you are absolutely doing it wrong and this can be so much easier for you
You should be using some sort of wine launcher, the popular one is lutris but i suggest using either bottles or faugus launcher, particularly faugus.
guide for faugus:
-use the gui app protonplus to download a recent version of proton-ge(i suggest 10-3 because i tested that one on votv already)
-install and open faugus(guide on the github, unfortunately looks very inconvenient to do on ubuntu)
-add the name of the game, pick the directory for the prefix(the default is good), and point to the location of the exe, and select the version of ge-proton you downloaded
-if you did everything correctly, it should just work without much struggle.
