I think that you may want to email support@glitch.com to get more space to clean the disk.
But you may be out of storage space. You can always check Glitch pricing for more space!
I had the same problem 4 months ago, and I have it now again…
Last time, a very kind person, @tasha helped me.
Maybe this time, luck will smile at our projects once again and we would receive increased space for the next 24 hours so we can clean our discs?
