My saved Projects with SPX500 are not loading anymore

Dear Team,

This is very important. I need to continue my backtesting, however, problems in loading the saved projects seem to be recurrent. It stays in the “loading” mode forever.

I was using Microsoft Edge. Tried several things: logged out and in, cleared the cache, changed to Chrome browser; “open previous”; nothing worked

The projects opening are the only ones using other symbols. All the projects with SPX500 that I have already started are not opening.

I will send the link of one project, but the same issue is applied to all my other projects with SPX500.
