Summary

I’m having trouble connecting to URC. At first, I was able to open my project normally, but I couldn’t sync or check in to the project; I kept getting this error message:

So, after trying for a long time to find any errors in the files, I decided to delete the project folder from my computer and try syncing again, but now I’m stuck on the loading screen, and the loading process freezes right when I try to connect to URC.
