While Google meet on personal profile works just fine, the one on work profile crashes each time when either starting or joining a meeting. The issue seems to be permission related:
java.lang.SecurityException @ Parcel.java:2071 (android.os.Parcel) “Neither user <user_num> nor current process has android.permission.INTERACT_ACROSS_USERS”
This issue seemed to be transient in the past because I used to get it fixed by turning internet connection off and on again, but maybe that was a different problem altogether. Today, it doesn’t go away even after cache/data clearing, reinstalling, rebooting, etc.
And now for the most useful info: I found a very similar issue described in OnePlus forums here which was later fixed by a system update.
