After switching computers, this is happening. Other computer had dedicated graphics card this one does not, This is the only difference.
Can you check if your PanelSettings has the Theme Style Sheet set?
Can you try right clicking and selecting “Reimport” on the UnityDefaultRuntimeTheme asset? There’s a current bug that it fails to load correctly (already being fixed).
I tried reimport, and ven reimport all nothing. I am getting those errors. And I am using Unity 2020.3.19f
This is still looking like the issue with loading the default theme style sheet properly, but other than reimporting the asset there’s not much I can suggest. Maybe recreating the Default Runtime Theme Style Sheet and assigning the new one to the PanelSettings, but if you had modified the theme that would mean losing those changes
I got this working. Thank you @JuliaP_Unity
Step I forgot to. Was when you reimport you have to swap the default style sheet in the Theme Style sheet.
Thanks for letting me know, but that doesn’t sound right to me. You shouldn’t have to do that. If it’s working for you that’s great, but using the asset should work as well.
