Disk 2 partition 1 has the word "System" next to it."...the system volume does not contain the required free space."
That might be a clue.
As far as I can make out from your miniscule picture, it is 100mb with 0mb free space.
Can install Windows 10 due to insuffient space on a 500GB partition

You didn't detach the other drives as instructed. You're playing with partitions and a small mistake can erase a drive.
Detach any other drives (SATA or Power cable) from the MB.
You have made so many boot changes that the EFI might be corrupted.
Lets rebuild the EFI partition
Open a CMD window as administrator and type:
diskpart
list disk (it will list all drives. Identify the main drive number)
select disk n (replace n by the main drive number obtained with list disk)
select part 1
del part override
create part EFI size=100
format fs=FAT32 quick
assign letter=W
create part MSR size=15
exit (to exit diskpart)
bcdboot C:\Windows /s W: /f UEFI
diskpart
select vol W
remove letter=W
exit
Reboot and try to install on the unallocated space

The above commands ruin your structure!
Do it like this:
diskpart
list disk (it will list all drives. Identify the main drive number)
select disk n (replace n by the main drive number obtained with list disk)
select part 1
format fs=FAT32 quick
assign letter=W
exit
bcdboot C:\Windows /s W: /f UEFI

Hi Megahertz,
I cannot delete the partition. I get this message (I am in command prompt as Administrator):
Kind regards,

Hi Pentagon and thank you for helping me out.
Unfortunately, I get an "Incorrect function" error when attempting to format partition 1 (confirmed EFI partition).
Kind regards,

Sorry,
Boot from a Win 10 installation drive and at the Windows Setup screen, press Shift+F10 simultaneously to open a command line prompt and type:
diskpart
list vol (take note of the Win 11 partition letter. It may not be C:)
list disk (it will list all drives. Identify the main drive number)
select disk n (replace n by the main drive number obtained with list disk)
select part 1
del part override
create part EFI size=100
format fs=FAT32 quick
assign letter=W
create part MSR size=15
exit (to exit diskpart)
bcdboot X:\Windows /s W: /f UEFI (replace X with the Win 11 partition letter found above)
diskpart
select vol W
remove letter=W
exit
reboot
If it boots normally try to install Win 10 on the unallocated partition.
