I'm not sure if you've already managed to fix it or not, but I had the same problem and only just fixed it then. What I did was go to configure force dark mode, and added the URLs of the extensions to disable pages. By right clicking and choosing 'Inspect popup' for my extensions, I was able to find the URL for each of them at the top of the tab, and then add them to disable pages individually. However, if you can't copy and paste the URL, you will have to memorise it unfortunately.
