This doesn't seem likely to be a problem with corrupted disk files, but rather a regression in the Leap kernel. I have the exact same issue and booting from an earlier kernel fixes the problem for me.
The last working version for me was: - 5.14.21-150500.55.52-default The following two versions don't work: - 5.14.21-150500.55.59-default - 5.14.21-150500.55.65-default I will file a bug report. Adrian
