Zwift Crashing on meet up

I am having problems with Zwift I have been logged on and riding no problem went to join a meet up and system crashes then reboot system log in again system sees that I have tried to join an event and tries to connect me and continued to crash.
Deleted and reinstalled Zwift allows me back on but no riders round me or crashes whichever it prefers
Any ideas?

Hope someone can help me
