Hi @alicelee1203, welcome to the community!
Could you share a few more details about what you're seeing? For example, which version of Photoshop are you using? And do you get that message when using a specific tool from the contextual task bar?
If you’re able to include a screenshot of the message, that would really help us get a clearer idea of what’s going on.
Thanks so much!
Alek
