I'm unable to reproduce, starts just fine for me. Please find what is missing in steps to reproduce or create a VM image where this is reproducible.
@myrrc, Arch Linux user here.
I have encountered this issue across multiple Telegram versions and system updates. In my experience, the problem often arises when Telegram fails to connect due to proxy settings. To resolve this, go to Settings -> Advanced -> Connection Type in Telegram. Change the default setting from Use system proxy settings to Disable proxy and try again.
@pasqualtroncone Thanks, however, the issue is that Telegram's UI is unresponsive from the start so I can't get to Settings.
This also reproduces after wiping all Telegram-related folders and downloading the latest version from the website.
I have a guess that installation of Steam (consequently, i386 nvidia libraries and drivers) may have had an influence on that.
I'll try to remove them and try again
I would rather suspect D-Bus services or OpenGL driver. In case of some system-provided D-Bus service hangs, it has timeout and usually it unhangs once the timeout is reached (~30s per request, likely to spend multiple minutes given that there are lots of requests).
Ok, yes, you were right, xdg-desktop-portal is to blame (unfortunately, I can't remove it as Steam doesn't launch otherwise)

This is the solution.
Thanks for the hints!
