I am observing the same using Big Sur 11.6 with Apple M1 chip. The iOS version has no impact. Tried on iOS 15 and iOS 14.2.1 with the same result. rvi0 gets disconnected after 10 - 15 seconds. Tried the suggestions from other threads like "csrutil disable". Did not fix it.
I have another older MacBook (Intel Chip) which is working fine.
