A similar problem on my MacBook Pro 15 2018 release, and on MacBook 12 everything went without problems, apparently the problem is related to T 1/2 security chips.

https://developer.apple.com/forums/thread/656753 - I have the same problem as described here, the problem is in the T2 security chip with BridgeOS
I used the solution suggested by macguy59 and RobChag, it solved the problem with the error at 12 minutes of installation, but after the initial installation, the system asks to restart the PC, I get an apple, the installation starts, the screen blinks and boots normally in the OS Catalina, tried to put on a clean Catalina OS, the problem persists.
On my MacBook Pro 15 2018 year, the same problem, however, on MacBook 12, I reinstalled it several times, there were no problems. So it's not a serial number issue.
Try this solution:
Important - Both Macs must have the same version of MacOS
"T2 BridgeOS resolves the issue.
I shall note, however, that restoring T2 BridgeOS is delicate and risky procedure. I personally had no issues whatsoever, but I've read multiple reports of failed procedure resulting into bricked hardware. If anything goes wrong, it guarantees a trip to Apple service as there's no DIY solution available.
If that's your only or your main machine I strongly recommend waiting for subsequent build or even the GM where this issue will most likely be fixed by Apple.
This being said, detailed instructions on reviving or restoring the BridgeOS can be found here: https://support.apple.com/en-gb/guide/apple-configurator-2/apdebea5be51/mac
