Hello again,
It seems to be a problem with the python’s qt web renderer that was updated recently. For now, you can use the option --disable-seccomp-filter-sandbox when launching anki but I don’t know what are the consequences of this. It solved the problem for me but It would be nice to have a proper solution.
This problem occurred once before and the solution was suggested here: Setting --disable-seccomp-filter-sandbox by default on Linux?
Hope it will be fixed again.
