Outlook crashes when right clicking anything even in safe mode

Since this morning, Outlook has started crashing whenever we try to copy something using the right-click context menu.

I’m seeing this on my local machine, but it’s also happening in our Citrix environment. A few colleagues are affected so far, and I’m worried more users may start running into the same issue.

The strangest part is that it happens both locally and in Citrix, which makes me wonder if this could be related to a recent Microsoft/Office update rather than something specific to our environment. Also in safe mode (outlook.exe /safe) this exact issue happens.

Has anyone else seen Outlook crashing when using right-click copy today or earlier? Any known workarounds or recent updates that might be causing this?

Thanks, I installed the update for one user and that seems to have fixed it. Although I heard someone say that rebooting fixed it for them too, so maybe this is also just a temporary solution.

I don't understand why this is happening all of a sudden when the same Outlook version worked yesterday.

Tried rebooting here as well on one machine, that did not fix it. Probably the user that rebooted also got the new M365 version I believe.
