Home Assistant very slow, all kinds of errors etc

Good afternoon,
Suddenly Home Assistant is starting to behave strange. It is really slow and I get all kinds of errors.
It starts with a notification:

Invalid config
The following integrations and platforms could not be set up:
hacs
Please check your config and logs.

The log shows:

Setup failed for hacs: Requirements for hacs not found: ['hacs_frontend==20210214110032'].

I am still able to SSH into the Raspberry Pi, however it is really slow. However, I am not able to login with FTP anymore (showing an error that the host isn’t communicating anymore since 15 seconds).

What can I do? I am losttt and desperately wanting to have it running again…

(Temporally) disable HACS, fix config, then enable again.

Can you please help me with how to do this?

Sorry, no. Don‘t use HACS by myself.

Hmm, maybe anyone else that can help?

Have you tried simply clicking on the 3 dots of the HACS Integration, and then click DISABLE?
