Stuck at "Loading Data"

[vantop77]

My Home Assistant version: 2021.11.4

My lovelace configuration method (GUI or yaml): GUI

What I am doing: Home page (lovelace dashboard is not opening). Stuck at loading data on computer browser and android app. I am not sure the problem is coming from "Lovelace-card-mod" but the browser console is mentioning it. What I expected to happen:

What happened instead:

Minimal steps to reproduce:

# The least amount of code possible to reproduce my error

# End of code

Error messages from the browser console:

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html". Strict MIME type checking is enforced for module scripts per HTML spec.

I'm not sure this is actually related to card-mod either. Is it still an issue?

Nope, it is not an issue any more, it was easier for restoring from backup than resolving it
