HA does not start anymore - Custom components


I am an idiot first. :wink:

I am using HA for a few years now, but did installation only one time at the beginning. So I habe no experience with the basic system running HA.
Today I wanted to integrate a new custom component in “custom components” folder and (I dont know why) copied a py-file directly into customs components directory. Now it does not start anymore.

I have only one question. How can I delete a file in custom components without running HA itself!?

Thank :wink:

Can I access with SSH? Can I access directly on SD Card?
