Costant error 500 after forking repository

I forked repository GitHub - alpinelinux/aports: [MIRROR] Alpine packages build scripts but while the repo seems to have been forked successfully I can’t access it, getting always error 500 (Internal Server Error) when accessing it
Cloning is also broken at the same way getting error 500.

I can’t even delete the fork to try fork it again since my repo …/settings page also gives 500.
I don’t know how to proceed.

Thanks for the support!
