lutris was updated to version 0.5.8.4 in the fedora 34 and 33 branches, but not in f35 and rawhide. Please make sure that older Fedora branches don't have newer versions of packages than newer Fedora branches (as this leads to version downgrades on distribution upgrade, among other things). It also looks like you accidentally uploaded a .src.rpm file as source file with this commit: https://src.fedoraproject.org/rpms/lutris/c/7248e83d519d3e3de6b6e7aaf651454058b7e693?branch=rawhide That was probably not intentional?
Good catch. Somehow I managed to miss this bug till yesterday, but it is fixed now.
