Bruh it's 21 opt with an obvious (..B) (R) switch which I thought I checked but I gaslighted myself.
I cooked the dr with 4c2e 5mover and then missed the easiest finish.
My brain is just not working today.

Note to myself: check 2+2 on both sides, don't miss obvious drs

I got baited by this:

This is just (U' R U) -> (F2 D' L D) ext of 10+4c3. (B2 U' R U) gives 4a1 4e (11) but I couldn't find anything there.
Bro, forgot to switch (U) U' R2 D' - F' which gives a 2c3 4e (10) and an easy 21

B' R2 B' // HTR (15)
[R2 B2 R2 F2 U2] // E slice (19)
[] = U D' F2 R2 F2 L2 U D // solved (21)

this is just an extension of
L (R' F D2 L) - (U) R2 D2 B' F2 D // 4b2 0e (11), which has an htr in 14, 2e+slice sth sth into 22 backup. 

You can actually get a 20 from this rzp by doing +2 ext:
L (R' F D2 L)
(U') U2 B2 U2 R2 D2 B' D // 4b2 2e (13)
B' R2 B' R2 B2 R2 F2 // finish (20)
