Mystery Error: IllegalArgumentException: context is null

[qole]

This morning I opened my phone to a screen with this error. I don't think that I had the Nextcloud client open when I put it on the charger last night.

Cause of error

Exception in thread "WM.task-1" java.lang.IllegalArgumentException: context is null

Looks like #11026, but this was in theory already fixed. We backported #13080 to v3.29.1 via #13098.

@alperozturk96 Any idea why this would still be happening in 3.29.2?

EDIT: Does it have something to do with 3.29.2 not being a tagged release?
