Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

Hi,
I am trying to run ComfyUI on a fresh runpod GPU instance, ComfyUI-Manager used to work on this setup just a week ago but, not the button is not showing up.

I have no other custom noders installed just the manager.

No error in run log:

```

But console log from inspect gives this:

```

```

I also tried to run this in incognito mode but same issue. I am on Mac m1 and there is no antivirus or ad blocker installed. Also tried it on different ports, but no help.

Also, when i try to load any workflow, i get this:

Loading aborted due to error reloading workflow data

```

This may be due to the following script:

As you can see ComfyManager button is not showing up:
