VS2022 No items in toolbox-CodePudding

Something has happened to my VS 2022 installation. When I open a WinForms solution (Net6.0), there are no items in the toolbox.

The project settings contain

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0-windows</TargetFramework>
    <OutputType>WinExe</OutputType>
    <RootNamespace>Flasher-UI</RootNamespace>
    <IsWebBootstrapper>false</IsWebBootstrapper>
    <PublishUrl>***</PublishUrl>
    <Install>true</Install>
    <InstallFrom>Disk</InstallFrom>
    <UpdateEnabled>false</UpdateEnabled>
    <UpdateMode>Foreground</UpdateMode>
    <UpdateInterval>7</UpdateInterval>
    <UpdateIntervalUnits>Days</UpdateIntervalUnits>
    <UpdatePeriodically>false</UpdatePeriodically>
    <UpdateRequired>false</UpdateRequired>
    <MapFileExtensions>true</MapFileExtensions>
    <ApplicationRevision>4</ApplicationRevision>
    <ApplicationVersion>2.1.0.0</ApplicationVersion>
    <UseApplicationTrust>false</UseApplicationTrust>
    <PublishWizardCompleted>true</PublishWizardCompleted>
    <BootstrapperEnabled>true</BootstrapperEnabled>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <UseWindowsForms>true</UseWindowsForms>
    <ImportWindowsDesktopTargets>true</ImportWindowsDesktopTargets>
    <Platforms>AnyCPU;x64</Platforms>
  </PropertyGroup>
...

I have tried all the suggestions I have found when searching. These include

Toolbox->Reset
Toolbox->Choose items, Reset
Updated VS to latest level (17.3.4)

I have loaded a WPF solution and there the toolbox is filled normally.

I tried another WinForms solution which uses .Net Framework 3.5 and again the toolbox is filled.

The project did work normally until recently. I can only assume that I have changed something in the project settings but I don't know what that might be.

UPDATE

updated to latest level
problem occurs with new .Net 6 Winforms app too
deleted .vs folder in existing solution

SOLUTION

Repair the VS installation and reboot.

My vs2022 had the same problem in the last update, but after I repaired it through the installer, it was back to normal.
