Clearing Caches on Mac mini M1

macOS Safari?

Did you clear caches using Develop menu?

Try "Empty caches" twice.

    Enable Develop menu.

Did you clear it twice.

I went to Library Caches, all caches were removed except Apple stored caches.

As soon as Favorites are replenished caches will be restored, to help faster browsing.

Purpose of emptying caches is to remove old possibly corrupt caches.
