Version 26.08 firmware update

Since I updated my forerunner 965 watch to version 26.08, I have been unable to sync my watch to my phone.  I have had this watch since Fall of 2024 and never had a problem.  I have tried everything including setting the watch back to it's factory settings and deleting all the data that I had on the watch including music.  I don't know what else to do at this point.  Any help would be appreciated.
