which Menu allows the complete and rapid loading of the application VS Studio 2022 Enterprise???

Question

Good morning;

I use VS 2022 Enterprise on an MSI GS70 (I7, 16 GB Ram, System under SSD...) under Windows 11.

- I open a small development application under VS 2022: the "solution" loads quickly, the *.cs code files are displayed quickly, the design file is displayed quickly.... but

the Toolbox remains empty for a few minutes even though I force the display using the "View Menu" and in the "Design" file, I select a control then right click to display its properties. There this window remains empty for a long time... the same goes for all the controls. Via the "Regenerate solution" Menu: no effect... I launch "Debugging": no effect. After a while, the "Properties" windows are filled and I can continue my development. I specify that in the “Generate in background” menu everything is activated. I can see that certain parameters are loaded in the background... but I ask you which Menu allows the complete and rapid loading of the application???

I don't see which Menu to activate to avoid this wait which can last 5 minutes. It is not normal.

Many thanks for your help
