Hi. Sorry to hear this happened for you. Some users experienced the same and others (even with 1,000 or so Venues) on a regularly-powerful server did not.
This issue was fixed right away and our latest versions shouldn’t be causing this on your site.
Could you please make sure all your Modern Tribe plugins (and WordPress core) are at their latest versions?
Once you verify you’re on the latest versions, please test to see if the issue is still happening for you.
If it is, please enable WP_DEBUG and WP_DEBUG_LOG (which will create a file on your server at /wp-content/debug.log if there are any WP_DEBUG messages) and share any debug messages you see while trying to replicate this issue and doing other things on your site relevant to this ticket (such as visiting your site’s home page, events page, single-event pages, and anything else you can think to do).
