All problems are resolved after removed all those auto updates on the top of Windows 10 22h2. Now, sysWOW64's 32 bit version of powershell.exe works well on Win10 22h2, and Visual Studio 2019 also works great again. There is absolutely no compatibility issues between VS 2019 and Win10 22h2. The problems were those automated updates on the top of Win10 22h2. It appears that Win10 22h2 does not allow the complete stop of auto updates, but only allow "pause auto updates for 7 days" as an option. After all, Win10 22h2 shows much better performance than the previous versions.
