Umbrel 1.0 does not work

Hello friends, I have a problem with Umbrel v. 1.0 : no app works for 6 days (not started), first of all Bitcoin node…
I tried flashing again with Balena Etcher Umbrel 1.0 on micro SSD, from Mac (OSX Catalina 10.15.7) … Umbrel starts and the various windows are visible, but the apps don’t start… What to do? Can you help me?
