Quoting here answer from @aibd from another thread (How to reinstall stock OS on Samsung Note 10 plus - #14 by prkfsz)
on the similar question.
Posting it here not to go too much OT there…
I wrote the info on the versions you asked about directly into your text. And i must admit my experience is not sufficient to really understand your answer. But it’s not only /e/ that is unflashable, the TWRP too. Nothing goes in…
@aibd sez:
This is something of a “rolling issue”, the important thing that can be a blocker for a month or so are the two Security Patch Levels (SPL). My interpretation, loosely speaking, might be that the device was “unflashable” that month, but hopefully one can wait for /e/OS to “catch up” with SPL.
Please tell us what you see for both SPL on your device
