Installing /e/ on al Galaxy S9 - interrupting after TWRP is installed

Hi e-community,
I tried to install /e/ with the easy installer. After I solved the problem, the programm was not starting (because I didn’t use an Admin-account on Windows), I am now stocked after TWRP is installed. Actually I think it is TWRP. Maybe you can give me a hint after looking at my screenshot and the photo of my phone, if it really is TWRP. I don’t find any possibility to choose “keep read only”, as said in the installation. So, here you can see the screenshot and photo.

If it is just a hint you need: Know your hardware - Samsung
To add to the hint: Know your hardware - Samsung

… and btw @sandroid, very much, welcome to the forum

it must be something like that :
