I run Visual Studio Community Edition 2022 on a M2 Mac under Parallels with Windows 11 for ARM64.
I got the application (.NET 4.8 Webforms) running on the local IIS, but not on IIS Express. IISExpress startup fails with "Error loading global modules".
PS C:\Program Files\IIS Express> .\iisexpress.exe /trace:error

For more information about the error, run iisexpress.exe with the tracing switch enabled (/trace:error)
Any idea how to fix that?
IIS Express ships with ASP.NET Core module by default. However, due to a known issue the bitness of ASP.NET Core module shipped in its ARM64 installer was wrong and that's the cause of this error you described.
While the ultimate fix should be a patched installer, which might not come quickly, you can open the applicationHost.config file (hidden in .vs folder of your project folder) and delete ASP.NET Core module from the module list manually.
