Opening a prompt (which I needed to create a RAID0 volume during setup with diskpart) was not able to locate OOBE in Windows/System32. This command is no longer available and it would help future users to take the answers here with a grain of salt. What might've worked for you is not garanteed to work with others.
.
I wonder if this is somehow related to using a RAID setup. I didn't think anyone used that anymore with SSD and NVme drives. Is it possible that the OOBE folder is in another location. It's been decades since I looked at RAID. This could be a factor.
It also appears you may be entering the oobe\bypassnro command too soon. You need to wait till you get to one of the graphic setup screens, then type shift F10 to bring up command prompt. Just a wild guess as I have not touched RAID.
Hope this helps.

Hi Johnny,
I have RAID0 on my laptop, and no problem using oobe\bypassnro with windows 11 MCT media. 🤷♂️
If we can know which Build number and edition, he is trying to install from his installation media, we can just try that out. 😉🤐
