Tricky! I’d try what @FoxxyDev suggested. If that doesn’t work, I’d suggest creating a share link of the project and saving it somewhere. You could then try these:
- log out and opening the project by pressing ‘edit code’ on the share link.
- open it on the same device but in another browser
- open it on a different device
