in the future, to find the best place to post your message, use the list here, https://community.adobe.com/ p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
We are sorry for the trouble. We are unable to replicate this behavior at our end. Would you mind updating to v27.2 and seeing if that helps? If not, would you mind resetting your preferences as suggested by Kevin and try running the app in safe mode to see if the same behavior happens there as well or not?
Kindly update the discussion if you still need assistance with it. We'd be happy to help.
