Long story short: i tried to install windows via bootcamp and it failed. I wanted my partition back but it also failed. I tried a few methods from different communities but nothing works.
On terminal diskutil now it shows "free space". I've tried everything (turned FireVault off, booting in safemode etc. ... The diskutility app also doesnt work.
I appreciate your help.
Greetings
iMac 27″, macOS 11.5
If you have two internal disks on your 2019 iMac, to install Bootcamp, these should be configured in a Fusion drive configuration, otherwise Bootcamp Assistant will not work. You can use resetFusion (How to fix a split Fusion Drive - Apple Support).
The following commands may need to be modified, if you reboot the iMac, which can re-order disks. Using the output you have posted, run
diskutil eraseVolume free free disk0s3
diskutil eraseVolume free free disk1s4
diskutil eraseVolume free free disk1s3
diskutil list
before we go further.

EFI NO NAME indicates that an external storage devices was connected to the Mac during the installation of Windows.
What is the year/model of your Mac (do not post the serial number)?
Maby because i tried to install it manually with a bootable windows stick, after it failed with bootcamp
Thanks a lot. now my disk is back to normal.
Excellent! If you want to install Bootcamp/Windows you will need to rebuild the two drives into a single Fusion drive.
