Thunderbolt 2 output to Thunderbolt 3 monitor causes continual restart on 2014 Mac mini running MacOS Catalina 10.15.6

I bought the LG Ultrafine 4k monitor through apple, but could not use it with my 2014 Mac mini running MacOS Catalina 10.15.6. I bought the apple Thunderbolt 2 to 3 converter and though the monitor appeared to work, it caused continual restarts. I mean continual -- it was impossible to use the computer at all for more than a few minutes, and in fact the computer would not even shut down. When shut down was initiated it would restart instead.

Switching back to my old monitor resolved this issue.

Mac mini, macOS 10.15

It could be possible that you have a bad adapter or a bad cable.
