Updating 3.6.2 score with 4.0 version causes an error on the main score page.

I've recently come across an error after updating certain scores. Most of my scores were created in Musescore 3.6.2 or lower; however, when I update them with 4.0 versions of the score, it causes an error on the main score page.

Error in question: "Oops! Score download has stopped due to an unexpected error. Please try again."
