today I updated my macbook pro 2019 with touch bar to the latest version of catalina, but when I did I did have a problem with touch bar. When I try to change volym or brightness the slider needs to load like it's showing a circle on the screen that loading and than I can change volym or brightness, to be honest that is very frustrating. Is this a problem? Is there a solution? Did anyone else had this problem?

Try resetting the SMC https://support.apple.com/en-us/HT201295
