sudo kmutil load -p /Library/StagedExtensions/Library/Extensions/RMEFirefaceUSB.kext
Thank you Nick for this! This works but after rebooting my Mac, UFX is not recognized again. I need to run that command every time I start my Mac to make it work.
Why is this happening and how to fix this?
My mac is Intel based Mac Mini 2018. I guess why I got this issue is that I most likely clicked the multiple security and restart prompts in wrong order that ended up messing up the installation and security permissions.

Edit: I noticed you and ABS managed to fix this through Recovery mode. I also opened Terminal in Recovery Mode, browsed to /Library/Extensions to check that RMEFirefaceUSB.kext was deleted. I deleted it before going to Recovery Mode using the earlier command you gave:
cd /Library/Extensions/
sudo kextutil -v 2 RMEFirefaceUSB.kext
In recovery mode, I then ran the kernel extension panic medic boot command:
kmutil trigger-panic-medic --volume-root /Volumes/YOUR_HD_DRIVE_NAME
After this I rebooted and after login, I got the Panic Medic Boot prompt saying that I need to grant permissions again to third party kernels when respective programs are launched again.
I closed the notification and I re-installed the RME Driver. This time it prompted asking the permissions again. Previously I have tried to re-install the driver dozen times but I never got the security prompt again. This time I was careful in granting the permissions in correct manner ie. when the Security prompt asked to grant the permissions to RME and asked to restart, I clicked "Not Now". Instead I restarted through the RME Driver Installer as mentioned in the instructions.
Now after rebooting and testing multiple times my mac recognizes my UFX II properly every time and opens Total Mix normally.
Hopefully this post helps others who might encounter the same issue. I hope the installation procedure could be made more bullet-proof and the instructions would highlight what are the correct steps more clearly.
