Title.
When I try to install any versions of proton with proton up QT just nothing happens. Launching it from the terminal gives me:

Using protonplus at least I get an error when it fails, launching it from the terminal gave me this:

Using the fallback ‘C’ locale.

I tried changing my DNS on my router, reinstalling both of them, restarting everything, nothing did anything. I wanted to try downloading the appimage version of proton upQT, but when I click on the donwload on it’s github page it just fails to load in with an error saying that there might be a typo in the url.
Finally after I almost gave up I wanted to try using a VPN, but after I launched the flatpak version of protonVPN it just failed to connect to anything and just disables my own internet.
Just tried GE-Proton 10-26 and it worked with no issues as always.
As customary, do you have anything layered? That’s always the first culprit I’m suspicious of. You can never know what layering might mess with. Try to share the results of rpm-ostree status
Also, did you modify any config files or anything?
I did not modify anything. My system is as stock as possible, that’s the reason I chose bazzite. I run the system update every bootup(almost every day)
I only have flatpaks installed and whatever came with bazzite(like lutris) My only “modifications” are getting the plugin for plasma that lets me use gifs as wallpapers, the candy icon pack and a hatsune miku themed mouse pointer. Once I tried installing waydroid but I messed it up somehow and just got rid of it, similarly once I installed davinci resolve but it crashed constantly so I just never opened it again.
Whenever I try to install either GE 10-28 or the latest cahcy proton all that shit happens. Also I just don’t know why my vpn can’t connect anymore.
Do you live in a country that blocks large parts of the Internet?
You should be able to resolve and access release-assets.githubusercontent.com in a browser. It will give you a 404 Not Found page, but it should resolve and load.

alright, now it seems to work, I was able to download the appimage, and I was able to download both GE and cachy proton with the flatpak version of proton up QT.
