"Run Simulator" error after deleting a screen

[TechnicalPBG2025]

Good morning,
I'm working on a graphics project on a 7 inch Riverdi display (RVT70HSSNWC00-B). I added a screen containing a video but I couldn't play it so I deleted the screen and ran the Run Simulator but it gives me this error:

I ask you kindly how can I solve the problem?

I also ask you what type of file and video size does the TouchGFX application manage?

Thanks

Hi @TechnicalPBG2025 

Aparat from deleting the screen within the GfxDesigner, delete screen folders from the project structure and 'generated' folder as well.

Delete these 3 folders

.\generated

.\gui\include\gui\<screen folder deleted in GfxDesigner>

.\gui\scr\<screen folder deleted in GfxDesigner>
