Zoom meeting won't launch after app crashed

[Onlineteacher1]

Lately it has happened a few times that while being in a meeting, the app had an error and crashed, the issue being afterwards it was impossible to start a meeting again. I tried to solve it by updating the app, restarting my computer, de-installing the app and installing it again, of which the latter worked so far.
But this morning it didn't work, and I suspect the problem is that after crashing the app still thinks to be in a meeting, which seems to make it impossible to start a meeting again. I also tried stopping the meetings from my 'task manager', but that also didn't work today.
Does anyone have ideas on what might cause this problem and more importantly, what I can do to solve it?

Many thanks!
