Can't reinstall Linux VM

[Sveik]

Hi there, sorry if this is something simple but I'm at a loss. I've downloaded a utm arm iso for a Linux distro for education purposes. I installed it, played around and messed around with stuff assuming I could just spin up a new VM, but when I tried to create a new VM the utm iso is greyed out. I can't find a way to do this. I've spent around 2 days trying to start from scratch, whenever I select install instead of open, it has the utm iso greyed out.

I've tried deleting the utm iso, I've uninstalled UTM, purged cached files, and reinstalled UTM and tried to install the OS and it's still greyed out. Even after reinstalling UTM, the VM has persisting files. I just want to start from scratch and I have no idea how to do it.

I've tried asking the discord, reading the UTM documentation, searching for videos and just can't find this information. Maybe I'm missing something entirely, I'm not sure, but any help would be very appreciated. Thank you.
