New Google Webmaster URL Inspector Rendering Issues

I am in desperate need of help as from the 22nd of February I have not been able to get the new google URL inspector tool to correctly render my pages. No developer that I speak with has any idea what the problem is and I am completely stuck. If you check googles cache in search results you will see that all my pages have not correctly rendered and I have checked all 20 above my site which all have the correct page render. It is not just a single page but the whole site.

The pages does not pass the render as my scripts do not load and I get other error for my js and css files.

To try to fix this I have:

1. Turned off all main plugins and tested, which did not fix it so there can not be a clash with one of the plugins
2. Switched template to see if that was the cause but I had identical errors
3. Turn off vanish cache
4. Turn off CDN (Cloudflare)
5. Spoken to Cloudflare who say everything is loading correctly and the issue is with the URL inspector and google bot.
6. Had the developers of my hosting company (Cloudways) to look into it and they could not find any errors.
7. Load scripts from footer
8. Change the loading order to scripts
9. Turn off scripts from running when not required on page
10. Tried using Rocket premium cache alongside cloudflare which did not solve it

I can not think of anything else to try in order to solve this and I have contacted a large number of professional developers who have also not been able to fix it. Please can someone help me know what is causing this so that I can get google to render my site correctly.

Could these setting be related to the URL inspector loading issues?
