Hey, @은혜39048352vvv5. Welcome to the Photoshop Community. I'll need more info to help you figure this out.
Does this happen when you use any specific tool? Please share the system info from Photoshop Help > System info > Copy & paste into a text document > upload & attach here.

- Windows 10/11: Users/[user name]/AppData/Roami
