Blurry Photographs WordPress 5.8.1

I’ve tried to

1. Use .png as an alternative of .jpg
2. Disable wordpress default compression add_filter('jpeg_quality', perform($arg){return 100;});
3. Change themes to check
4. Disable plugins
5. Regenerate thumbnails a number of occasions
6. Re-upload media many occasions
7. Outline precise width and top for every picture
8. Disable lazy loading

The pictures nonetheless look blurry as soon as they’re uploaded. My pictures are all optimised and within the precise width and top. I did not have these points with earlier variations of wordpress. What else ought to I do to resolve this?

Thanks
