I was interested in trying out openSUSe and tried to install it on my third drive:

on my first and second attempt the install failed with an error that the creation of the efi Boot partition failed
something along the lines of:

execution of command /usr/sbin/shim-install failed no space left on device
(i tried both manual and automatic partitioning)

i then tried to install fedora on that disk, just to see if something is wrong with the disk (or my skill) and it worked without a hinch.

after that i tried it again with tumbleweed and it seemed to install just fine.
but when i tried to boot it didn't work,
it just showed a black screen with a blinking - for about a minute before rebooting.

i gave up after that.

is there something that i might have missed during my install,
i thought that openSUSE has a great reputation.

system is a ryzen 7 with an rtx 2060,
on an ASRock mainboard with secure boot deactivated.
disk is my old 250gb samsung 840 evo

i am having trouble with ipv6 in a specific program. (sf6 steam version)
completely disabling it has resolved my issues.

but this solution just doesn't sit well with me.

is there a way to only block that one problematic program from using ipv6?

I recently started playing sf6 in online mode.
Playing against other pc users seems to work just fine,
however Crossplay matches fail with the error code 50200-21018 (as far as i understand the first digits designate the http status code 502)

I talked to a steamdeck user for which crossplay worked just fine I play on silverblue using the flatpack version of steam.

At first is Suspected problems with the proton version,
and tried several diffrent versions (including GE) However this did not help.

Updating my ostree and flatpacks did also not help.

does anyone have suggestions on what might be causing these issues, or how to debug it further?

EDIT: same error occured when i tried using the steam version from the os
