Comment 1 Albert Astals Cid 2024-02-09 22:42:11 UTC 
Had you opened kwordquiz before or this is the first time starting it?
Comment 2 Thomas Bettler 2024-02-11 15:51:45 UTC 
Seems related to several failures not being caught in application:
- file permission: file open not allowed
- xml from earlier version: xml nodes/attrs in container > lesson - failure not being caught
Comment 3 Albert Astals Cid 2024-02-12 16:23:49 UTC 
Are you going to work on a code fix?

Otherwise i feel like we need more info. You seem to have identified some issues, would be great if you could expand on them a bit more
