@A0Cyber I am experiencing the same situation. I have just started experimenting with M5 gear. I got 2 x M5 Stick C Plus2. The HAT works fine, however Grove ports worked for a short time and failed on both sticks.
I Started doing some tests in UIFlow 2.2, version 2.3.8 with a Unit, that went well. Proceeding some tests with ESP Home on the same devices, Noticing that the Unit did not respond. Back to UIFlow, and now the Unit failed.
I ran the Project Zone called: M5StickCPlus2_GPIO32_GPIO33_ON_OFF_UiFlow2.2.0 and noticed that PIN32 was less than 1 Volt. So to me looks like some hardware issue, but what went wrong? Still not clear to me.
