Can no longer load a sequence without error

Hi, 

On or about 25 Mar 2024, I submitted 2 observations of R Cnc in V and B using my sequence named FPIA_R_Cnc, successfully.

The images I used are still in my list of images, dated 2024-03-25 01:04:44 for V and 2024-03-25 01:00:46 for B. 

I can no longer load the same sequence I used for the report I had submitted. When selecting the sequence the following error dialog box appears immediately:

"One or more stars could not be identified, meaning that no star was found in an 5 arcsec radius around the catalogued position. Reasons for this could be:"

etc., etc., 

This also has occurred with sequences I created yesterday (3 April 2024) and no longer work today. 

I am using Chrome.

Did any software updates take place recently?

Thanks!
