I'm pretty sure I just found the issue. My campus just deployed Cisco Umbrella, which is apparently blocking one of the URLs used for accessing projects without throwing an error message directly. The only way to find out that the URL was blocked was to go into the console through Chrome dev tools, find and click that specific URL (which I've highlighted in the below picture), and be brought to a screen notifying the user of the block (which I've also attached). Otherwise, the user would simply see a loading screen that never ended.
I've confirmed this is most likely the issue by trying to open my projects through my mobile hotspot, which worked fine. I'll have to contact my school's IT department immediately to get this whitelisted.
Thanks for your help and responses throughout this issue!
