@ferophila : to narrow it further down: Do you have the same problem in 2.1.54? You can have both anki versions installed at the same time. On MacOS in the folder applications/Programme before I install a new Anki version I rename the old Anki to something like “Anki54qt6”. Only after this I install Anki 2.1.55 (which will have the default name Anki). This allows me to quickly test with older versions.
