I can not set up my Agent it always crashes

I’m trying to set up a tunnel for Foundry VTT, but it’s failing right from the agent stage. I try starting a new agent, but it’s permanently offline, and the program shuts down automatically.

I’m using the latest version and have reinstalled and uninstalled it several times.

Does anyone have any idea what the cause might be?

What OS are you on?
What version are you trying to install?
How are you installing it?
How are you running it?
