Deleting multiple ways fails

[anonymous]

What steps will reproduce the problem?

1. downloading ways from OSM
2. Selecting multiple ways or sections of ways
3. clicking delete

What is the expected result?

The ways and nodes are deleted

What happens instead?

Nothing gets deleted and an unexpected exception pop-up appears

Please provide any additional information below. Attach a screenshot if possible.

I select multiple (sections of) ways and their nodes with the select tool then delete them, the operation fails and pop-up appears. This only happens with ways and relations imported from OSM. This has happened sporadically today and trying again usually works, it did not happen at all when i last worked on this project (5/12/2024)
