can't edit data anymore

[Polyglot]

What steps will reproduce the problem?

1. Simply attempting to open a file
2. Or to download data in a new layer

What happens instead?

Crash and burn, i.e. nothing

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

When I downloaded this version, everything was fine. It seems to have something to do with my keyboard shortcuts

It works for me. This looks like action get assigned shortcut without modifier and org.openstreetmap.josm.tools.Shortcut.getKeyStroke() return null if modifier is not set. But there should probably be some warning about shortcut reassignment. I can check it deeper on Monday but now I'm running of of battery.
