Permanent reboot after disabling apps with Shield TV version 2.1

I’ve recently uptaded my NVIDIA Shield TV with version 2.1.

All is ok to begin with, but when I change notifications to off (in order to have a clean screen at startup) and disable added applications, such as Google Play Music, games, …

the box keeps rebooting.

All this was ok with version 1.4

Any cue ?

Can you detail the exact steps you took (that you can remember)? I’ll have our QA team take a look and see what is causing this issue.
