Hello @omnimj
You will never be able to install the TWRP, once you have started Android 10, it will permanently lock the mounting of partitions by TWRP from the start of initialization.
I advise you to read and understand my tutorial which was duplicated at post # 341
If you don't understand what you need to do, you will never get there.
I can not help if you do not follow this tutorial and respect the "IMPORTANT" phases mentioned.
cordially
Hello @montero70, thank you for your quick reply.
I've already passed through the procedure that you described in the post # 324 from 06 February 2020.
Unfortunately I didn't manage to get TWRP that works well. I got boot-loop, missing partitions, I couldn't restore, my phone stocked several times etc.
I have also tried other suggested procedures, but no positive result.
I realized that in this stage is not possible to get TWRP properly working with the available tools and decided to root my N9 following the tread [Guide] Root Note 9 (Exynos) Android 10 (Q) With/Out Custom Recovery posted by Zer0De8th, Junior Member on 24th January 2020.
So I got into the current situation of having a rooted N9 on Q, which works fine. But, I'm still missing TWRP and I wouldn't give up.
I will listen to your suggestion and try again instructions that you gave at # 341 post. I saw the twrp-3.3.1-r3.8-Q-crownlte has been published in a mean time. Shall I try it instead the twrp-3.3.1-r3.7-Q-crownlte that you suggested in #341?

Why are you messing up by doing all steps that even doesn't requires for N9 which is not true SAR like s10/N10
Here very simple steps to get twrp and root on Note9 with Android 10
- Flash stock Q
- oem bootloader unlock
- flash twrp - reboot to twrp - flash latest stable magisk
- reboot twrp
- flash dm - verity disable force encrypt (link below)
- reboot twrp - format data (that you need to confirm by typing 'yes'
Reboot to system and done!
Here already I have explained on how to root thread

Hello dr.ketan. Thank you for the reply.
As I have already described to Montero70 how I came into this situation and I wouldn't repeat myself.
I'll try yours and his procedure and I guess one will manage to get TWRP that works fine.
All the best.
