Tried to install dinput dinput8 d3dcompiler_43 d3dx9 dxvk122 vcrun2005 vcrun2008 vcrun2017 devenum

and actually the whole Protontricks just "goes away" from screen after clicking OK (assumably it should start to download this stuff). Ad then later on comes:

Note: command /home/tux/.var/app/com.github.Matoking.protontricks/cache/protontricks/proton/Proton 9.0/bin/wine64 C:windows

Protontricks Flatpak.

There are now also these dialogs appearing:

"Working around wine bug 50894 -- Working around failing wusa.exe lookup via C:windowsSysNative"

"Running /home/tux/.var/app/com.github.Matoking.protontricks/cache/protontricks/proton/Proton 9.0/bin/wineserver -w. This will hang until all wine processes in prefix=/mnt/a842d9ab-8953-4894-be6c-97a7fc75276c/SteamLibrary/steamapps/compatdata/316160/pfx terminate"

Could possibly be a Winetricks/Wine related issue instead of Protontricks. Could you try running using the --no-bwrap flag like so to check if that solves the issue?

$ flatpak run com.github.Matoking.protontricks -v --no-bwrap APPID -v dinput8 d3dcompiler_43 REST_OF_VERBS_HERE

If that doesn't work, one common solution is to destroy the Wine prefix (i.e. the game-specific "Windows" environment) using "Select the default wineprefix" -> "Delete ALL DATA AND APPLICATIONS INSIDE THIS PROTON PREFIX", and then running the game again through Steam again. This can be helpful especially if the same prefix has been used with multiple Proton installations. Note that this will also delete any local saved data for the game.
