Cannot save scene

Summary

After uploading materials I am unable to save the scene.
At least, I waited for over 10 mins to save and then gave up.
I decided to try a previous model that I already have in my listings.
I knew it saved in under a minute.
This also hung, after a few mins I gave up.

Additional Notes

I noticed that the bar showing the upload progress isn’t showing when trying to save. See attached image of trying to upload the model I already have listed.
