Hi, version 14.7 consistently crashes with a 'serious error' when editing a multicam sequence. Especially with adding audio tracks, or making cuts on the timeline.

All sorts of issues started with 14.4 and have sadly not improved in versions up to and including 14.7 
Unless you have time to pay Adobe to Beta test their software, rollback to 14.3.2
