Remove the raid drives from the system. Plug in spare non raid drive and see if it installs on that.
Do you otherwise meet all the requirement of win 11 with a MS account?
I use raid as storage devices for large media files but the latency kills the low que depth speeds horrendously and actually makes an OS run slower. When you think about it almost all of the OS files are small dll files 4kb. Raid0 kills that. Looks impressive for sequential reads of large files but kills the Q1 4K performance in a bad way.
Heres an example for you. All optane drives. One is a 905P that I run my OS on and the other is a pair of optane M.2 drives in raid 0 that I have games loaded on. I have other SATA raid arrays for media storage but thats another story. Samsung drives M2 drives arent very good in Q1 4K to start with and putting them in raid is horrendously slow in Q14k, thats the last example just one all by itself non raid is less than half of the Intel drives in raid and not even close to a single Optane.
905 P all by itself

M.2 Optane drives in VROC raid 0 (this is more comparable to the 905 by itself in Q1 4K)

Now the single Samsung 970 evo plus.

Sure the big numbers in sequential reads look cool but in the end they don't do you any performance favors unless you just copy 1GB files from drive to drive all day. The snappiness of the OS is dependent on the Q1 4K. I put a pair of Samsung 960 pros in raid Zero and dont have a screen shot of that but it was pitiful in Q1 4K, like 20 MB/S although the sequential was up there pretty high.
If trhe single drive doesnt work out then you should be able to remove that and just plug your raid drives back where they were and be back in business just as it was.
