for the last three weeks I've have meetings with 45 to 90 people in them, and there are at least six people who have the same link and password who cannot get in, including people who work for me and use zoom daily.  I never had this issue before - has zoom changed?  I'm not able to continue with Zoom and am looking for alternative platforms if this can't be resolved.

There doesn't seem to be any support either.

These are not people new to Zoom, but they are able to come in on their phones, just not computers.

Any help with this?

Greetings, I was attending an online class when Zoom started to crash consistently whenever I tried to join it.
After an update, I thought the issue would be resolved, but alas it persisted; I then looked online for answers, and some suggested that changing my video settings might help, but whenever I even so much as click on the video settings or the screen sharing settings, all other settings options work normally, Zoom crashes again.
Reinstalling the app did not work either, so I was forced to go to the support page hoping to find a solution, only to be met instead by a paywall between me and the support team; as such, this forum is my last hope of being able to go back to attending my classes, any assistance would be appreciated.
