Hi Everyone...
For those of you on the beta channel, be advised that betas are intended for testing purposes and the beta experience includes breaking various functionality. No manufacturer supports a beta OS, not even the OS vendor. Betas are the last steps in the test process before a new OS is released.
That being said, this is a known issue and will be resolved as soon as possible after Apple releases the source code for Big Sur.
The workaround is to manually load the driver, there have been no reports of this not working.
The process is below. The first command checks to see if the driver is loaded. The second command loads the driver. The third command verifies that it is loaded.
tests-MacBook-Pro-14:~ test$ kextstat | grep -i stex
tests-MacBook-Pro-14:~ test$ sudo kextload /Library/Extensions/PromiseSTEX.kext/
Password:
tests-MacBook-Pro-14:~ test$ kextstat | grep -i stex
190 0 0xffffff7f83b17000 0xd000 0xd000 com.promise.driver.stex (6.2.13) AE253556-66D8-38D2-B9D1-179B78F29153 <183 13 6 5 3>
tests-MacBook-Pro-14:~ test$
Once loaded it may take 10 or 20 seconds for the drive to appear on the desktop.
One last thing, I do not have Big Sur beta to test with, but Catalina broke a lot of things in that extra permissions have to be granted to run many kinds of software. It's possible that Big Sur has additional permission requirements for drivers to load, checking Settings > Privacy & Security > Privacy for any unchecked premissions for drivers or Promise devices would be a good idea.

Reloading the posted driver DOES work. You just need to force quit the installer before it reboots. Restarting the computer repeats the problem.

Same problem here! R4 not recognized after booting into macOS 11 Big Sur beta (20A5384c).
The above workaround with the 'kextload' works but can only be a temporary solution while testing the betas. This should be fixed latest until the official release of Big Sur.

It look like the issue was resolved in macOS Big Sur Beta 11.0
