The "unknown file arch" warning is an upstream issue with Winetricks: see the issue report at Winetricks/winetricks#2183. There are some proposed fixes in development, but none have been merged yet.

That said, you should be able to close the warnings and continue. Is there any output afterwards once you do so? What if you run protontricks <APPID> -v? This prints a lot of output, so you'll want to use gist.github.com to post the output.

Figured out what's the problem: the Debian version of Winetricks includes an additional patch that's based on an old version of the pull request Winetricks/winetricks#2189. It's the 13_winetricks_get_file_arch__try_workaround_for_scripts_if_arch_is_unknown.patch file included in the Debian source files here.

This patch also changes the "Unknown file arch" message from a dismissable warning to an error that halts execution.

One option to workaround this might be to uninstall the distro version of Winetricks and install the upstream version using the instructions here:

An addendum to my last post, I did a clean install of Arch (via archinstall) on a new machine with nothing on it except for the requirements to run protontricks, winetricks, steam, etc. All of which were installed via flatpaks when possible. I didn't get any errors this time but now I get stuck in a loop of "what do you want to do with this wineprefix" (install windows dll or component) and "what would you like to install". I select what I want to install and it starts the loop over again. I've legitimately clicked through this about 10 loops and it will not go away.

The "unknown file arch" error should be fixed assuming you're running the development version of Protontricks and Winetricks. A fix was added to both fairly recently.

The warning is only related to a check that Winetricks performs, and any other problems (eg. looping menus) are unrelated. The looping menu in particular is related to Winetricks and is probably out of scope for Protontricks.
