Google Search settings

My Google search settings keep resetting.

My theme colour, my location and trending searches all keep resetting back from what I changed them to.

I choose dark mode for my theme, I turn trend in searches off and I choose my location as UK.

It always use to just stay that way until a recent update, now on different browsers where I’m signed in it keeps reverting back.

I deleted the cache and all data from all browsers search engines chrome, brave, I have set my preferred browser as default, I have even uninstalled browsers and reinstall them.

It is affecting my Android phone the worst, after 5 minutes of setting my search settings it resets and my screen is light, trending searches is back and my location has changed to current location. It is really annoying me, I cannot seem to get it to stay the way I want it to.
