Checklist

• [ X ] I’m running the newest version of HACS https://github.com/hacs/integration/releases/latest
• [ X ] I have enabled debug logging for my installation.
• [ X ] I have filled out the issue template to the best of my ability.
• [ X ] I have read https://hacs.xyz/docs/issues
• [ X ] This issue is related to the backend of HACS.
• [ X ] This issue only contains 1 issue (if you have multiple issues, open one issue for each issue).

Describe the issue

After installation of HACS following the docs (https://hacs.xyz/docs/installation/prerequisites), the install script runs correctly, GitHub authorised correctly, system restarted and HACS option allowed to be selected for integrations. Once it appears the setup obviously hangs and the following error is shown in the logs. Unsure of why it is struggling to read the manifest.json as it’s definitely in the custom_components folder.

Steps to reproduce

1. Install of fresh version of Home Assistant OS (Raspberry Pi 3B)
2. Install of HACS using docs and install script completing correctly, GitHub authorised
3. Restart of HomeAssistant Server
4. Integration added for HACS
5. HACS menu item shown on SideBar but set as constantly installing, errors shown

That’s just bad luck, it will be fixed later today. in /config/custom_components/hacs/manifest.json, change "aiogithubapi>=21.2.0" to "aiogithubapi==21.2.0" and restart Home Assistant

I seeing the second error after upgrading to version 1.12.1 after trying to upgrade to version 1.11.3 and getting a “HACS is starting up” message that lasted over night and through numerous restarts of HA.

In Firefox have tried Ctrl-F5 to clear the browsers cache used the browser settings to clear cookie and data for my HA url and this did not get rid of this message. I had to log in to HA after doing this so it clear cookies and it said it should clear any data. If I open the HACS page in Chromium or in a Firefox private window, I do not get this message. So it does look like it is a browser cache issue but I cannot seem to get it out of Firefox’s cache. Restarting Firefox also does not help.
