I purchased a Belkin Thunderbolt 3 Cable (100 watts, 6.5 Feet/ 2 Meters, F2CD085bt2M-BLK) from Amazon for to connect my 2020 27" iMac to my Universal Audio Apollo x8p audio interface. When I connected the cable, it caused my iMac to shut down. The crash report said it was a kernel panic.
I am returning the Belkin cable and ordering an Apple Thunderbolt 3 cable. But has anyone else experienced this issue?
27" iMac
**SOLVED**
When I connect my Apollo Twin and Apollo x8p using the two Thunderbolt 3 ports on the back of the iMac, all the cables I've tried (Belkin cable, Apple 0.8m, Apple Pro Cable 2.0m) caused the iMac to crash.
When I connect *just* the Apollo x8p to the iMac then connect the Apollo Twin to the 2nd Thunderbolt 3 port on the back of the Apollo x8p, everything works properly.
I'll make Apple and UA aware of the issue.

Could be the Apollo that has the issue. Have you used it on another Mac?
I have not but I also try to keep my TB cable as short as possible as TB devices are sensitive to TB data/power transfer issues.
**UPDATE:**
The Apple Thunderbolt 3 Pro Cable (2m) did the same thing.
I'll try with the 0.8 meter cable...
Yes, I was able to use the Apollo on an older 21" iMac
