White screen with EGPU only connected

I'm using a Radeon RX580 epug with my 2018 mac mini. If I try to boot with Catalina with only the egpu connected I just get white screen on boot. However if I boot with a combination of a monitor attached to the hdmi port and the egpu connected to other monitors, then the mac will boot correctly. It's very strange because the egpu works, but not without a hdmi display connected to the mini. Has anyone else had this bug and any suggestions? For now I'll just keep a hdmi display attached.

Mac mini 2018 or later

I can confirm that the latest public beta does fix the issue. It seems like it also did a firmware update to the MacMini. It's crazy that Apple would break something so important and never comment on the issue. But they seem to prefer quietly fixing issues without ever admitting there was a problem.

I thought the main problem was with the RX570 to 590 cards?

I don't have a Mac Mini, but I experienced the same problem (DisplayPort signal but black screen) with my macbook pro, eGPU and Radeon RX590, and LG5k2k monitor.
