Hope you've already managed to clear the error - if not, I have a few pointers, and can probably give you more with a little more information.
Let's start with the obvious - have you already power cycled everything? As in, power down the robot, disconnect from circuit, wait to let all caps bleed off, then reconnect and power on.
Next: are there any error messages? If so, can you share screen shots?
Also: if possible, open another method - do you get the same behavior?
Lastly: each of the arms (assuming you have a standard 3-arm config with a RoNa, an MC96 and a LiHa) should be running their own homing routine during initialization - do any of them complete correctly?
Feel free to DM me if you're still stuck.
