Bookings Page - Some Error Occurred

Having an issue with a Microsoft Booking page where it keeps encountering the "Some error occurred." when loading.

This Bookings page was confirmed working from creation date of May 14th, 2026 to recently, September 14th, 2026. As far as the user has told me, they had changed nothing between those dates. I had worked with the user and tried the following troubleshooting steps:

1.) I had the user switch the publishing from "Available to anyone" to "No self-service". Confirmed that the page then started showing a "Bad request" error and then changed the setting back to "Available to anyone." This did not fix the issue and the "Some error occurred" was still happening. 

2.) Confirmed with the user if there was anything that changed that might be causing syncing issues between the staff calendars and the Bookings page. Found two instances (1 user who had they name changed and 1 user who went on leave of absence) and decided to see if these might be causing issues. The user who was on LOA was removed and this did not fix the issue. The user who had their name changed recently was appearing with the correct names in other Bookings pages but still had their old name in this one. Once removed and readded to this Bookings page their name was updated to be correct, but this did not solve the issue.

3.) I had the user check to see if the automated emails from the Bookings were still sending and they were confirmed to be sending. These automated emails do have specific Service links in them that are being received by customers and are working at this time.

In regards to the above point, while I was working with the user who created the Bookings page, we found that the Calendar in the Bookings page was not working correctly. It does not show the Bookings that were created consistently and would usually appear blank. The Services that were created have all disappeared, but it looks like a filter is being forced. It shows "Services 52 of 0" and the user tried to remove the filter and nothing occurs. 

What are some next steps in troubleshooting the Bookings page?
