Why does Google Photos say nothing to free up?

After google photos backup my photos, I have the choice to free up 6.22 GB. When I click on the button to delete these photos nothing happens. If I click on the button several times I get kicked out of the app. This is the first time that I have issues like this. I don't know if its the Google Photo app it self or my new S21 Ultra has the problem. I uninstalled the Google Photo app like 5 times, I reset my phone twice and I made sure all the app were up to date. Does anyone knows how to fix this problem?
