Annotated dataset upload stuck at 0 seconds

I am having issues with uploading any annotated dataset within a project. The annotations are masks, and it is an instance segmentation project. I am using Mozilla 113-64 bit on Ubuntu 22.04. The upload seemingly completes, but the app doesn’t provide the “upload complete” notification, and it doesn’t redirect to the dataset section. It just stays stuck on 0 seconds, for hours at a time.
