'Visual Studio 2022 WinForms designer hang on "Loading Designer..."

When I try to open a WinForms designer in my startup project in a solution, I get a screen "Loading designer...", "You can continue working while the designer is loading in the background". This screen stays forever and the designer is not loading. This seems to happen in any form or control in the project.

If I try to open the designer for another form in another project in the same solution, I get this screen but after a few seconds, the designer is opened.

I tried to clean the project, delete the ".VS" directory, reboot the machine, nothing helped...

Any ideas?

Solution 1:^[1]

I had the same issue.

Copy all the files in the project directory.
Create a new project using the template "Windows Forms App (.NET Framework)" not "Windows Forms App".
Then copy all the files from the old project.

Solution 2:^[2]

I had same problem. I tried Restore Nuget Packages and problem solved.

Select Tools -> Options -> NuGet Package Manager then check Allow Nuget to download missing packages.
Right click on the solution and select Restore Nuget Packages.
Close the solution and reopen it.

don't back up your projects with OneDrive
don't give administrator permission to framework or dotnet or visual studio and don't install that way

Solution 4:^[4]

I had the same problem.

Solved by running VS 2022 as Administrator.

and wait for Nuget Package Update

first, you must check NuGet Packet Manager Tools -> NuGet Package Manager -> Package Manager Setting

popup form, click NuGet Package Manager -> General in this tab check "Allow NuGet to download missing packages".

move to down tab "Package Source" if you just have one source is "Microsoft Visual Studio Offline Packages" you just add a package from API NuGet

click oke and taraaaaaa did it work
