Whenever you click inside the color picker for a Linearcolor within an editor Struct, the color picker closes out immediately. This can sometimes crash the editor. I’ve also had it where I wasn’t able to play in editor because the editor still thought the color picker was open.
Steps to reproduce:
Open a project Create a struct in the Content Browser Add a Linearcolor variable to the struct In the default value section, click the color to open the color picker Enter a value in any of the boxes or click somewhere in the color wheel Experience it closing immediately or crashing
