I was wondering if a geostationary satellite has ever broken up before. I found a NASA list of satellites that fragmented:

History of On-orbit Satellite Fragmentations, 16th Edition

https://ntrs.nasa.gov/api/citations/20220019160/downloads/HO...

Searching that PDF for "geostationary" I found:

"The Russian government’s disclosure of the Ekran 2 battery explosion on 25 June 1978 is the first known fragmentation in geostationary orbit."

There are two other geostationary fragmentations in the list, Ekran 4 and Ekran 9. These two events are hypothesized to have also been due to battery explosions.

AMC-9 and Telkom-1 both broke apart fairly recently too.
