Hi @elipie
Welcome to Microsoft Q&A!
You need to uninstall Visual Studio first and then reinstall it.
The first step is to uninstall Visual Studio, you can refer to this document to run InstallCleanup.exe, it will remove the VS installation files and product information.
If you cannot find the InstallCleanup tool, you can refer to this document to try to uninstall Visual Studio using the uninstall command in CMD.
After the uninstallation is completed, you can download the latest bootstrap program to install Visual Studio.
If your issue still persists, feel free to let me know.
Sincerely,
Peng
