Avogadro (1.101) crashes in my windows 11 when trying to open an output file from ORCA with orbitals

That certainly helps, yes. Have you tried with other file formats? For example if you create a .molden file with orca_2mkl file -molden or download the molden file from the other thread does it also crash?

(I’m trying to figure out if it’s related to the orbital display or reading ORCA in particular)
