Error in Editor 'tool.frame'

Hello everyone,

Has anyone encountered this issue recently?

Since one of the latest updates, I'm occasionally getting the following error:

EventSystem [9,206] Error calling event 'tool.frame' on 'Editor.CloudLocations'

Once it starts happening, the error is logged every frame.
It seems to occur randomly after entering Play Mode and then persists even if I unload everything from the scene or open an empty scene/project.

The only workaround I've found so far is restarting the editor, which immediately fixes the issue until it happens again.

Has anyone else experienced this, or found a way to identify what's triggering it?

Unfortunately, I don't get any additional information besides the message above.

Thanks!

Edit :
Error starts right after saving a system scene.
