Bootcamp volume is unremovable
I installed windows on my MacBook. In the Bootcamp assistant, I did the partitioning on battery (I had around 90%, so I though it would be fine), During the setup process I couldn't select English UK as the UI language, the time zone from Berlin/Bern/Geneva and the Swiss currency, with the Swiss German keyboard setup, it kept giving me an error that it is an invalid UI language, so I quit the setup process with the red arrow on the top right, it warned me if I wanted to leave setup and I clicked yes.
After this I restarted into the Mac because I had to take some notes quickly. After a while I tried to boot into windows, but now there was a blue error screen saying that my PC couldn't start properly, I tried to connect an external keyboard and clicking F1 to enter recovery environment but that also didn't work an brought me back to the error page. I tried to go in to Mac Recovery mode and then using disk utility to delete the bootcamp volume and restore the space back to the original partition, but I keep getting an error saying that I don't have enough space?? I don't understand how I don't have enough space to get space??
I have tried erasing the bootcamp partition and then restoring it, but I got the same problem, what can I do??
(I have made Time Machine backups btw, but don't aim on factory resetting the whole device because then I'll have to reinstall every app again)
