My Umbrel node keeps acting strange/crashing yikes!

I review a lot of Pi forums and bad (slightly low voltage) power supplies are really common, so it’s probably the power supply.

To check for undervoltage, connect to your RPi via SSH and run this command: 
vcgencmd get_throttled.

It should say output throttled=0x0, If it does not then either the power supply or your SSD is using too much power. You should order an official Raspberry power suply.
