Hi guys, if you own a Samsung Watch Ultra and a Samsung Z Fold 6 then you might have this problem too if your Samsung Watch Ultra is charging on the old slow charger of the Watch 4, 5 or 6:
Each time you open an app on the Samsung Fold, it closes after a few seconds. The reason is that the homescreen pops up because the Samsung Fold reacts on the failing charger of the Samsung Watch 4, 5 or 6.
Solution: don't use the previous watch charger on your Samsung Watch Ultra.
