[AOT] LINK : fatal error LNK1123: Failed during conversion to COFF: Invalid or corrupted file

I TRY uninstall 7.0.5 but 7.0.302 for visual studio cannot to uninstall or replase 7.0.202 for visual studio

C:\Program Files\dotnet\sdk\7.0.302\Sdks\Microsoft.DotNet.ILCompiler\build\Microsoft.NETCore.Native.targets(350,5): err
or MSB3073: 命令“"D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.36.32532\bin\Hostx64\x64\link.
exe" @"obj\YTLSX_R\net7.0\win-x64\native\link.rsp"”已退出，代码为 1123。 [D:\dev\company_project\WEB_webapi\webapi_mes\webap
i_mes.csproj]

Because there was a problem with the code running after AOT was compiled, I deleted many .net 7.0 version folders on the computer and uninstalled it, resulting in this problem that cannot be fixed regardless of whether it is reinstalled or not.

It worked fine before reinstalling the computer, and now a simple sentence can cause a crash, and I tried using version 8.0 later, but there was a problem and I had to downgrade back to 7.0

error LNK1123: Failed during conversion to COFF: Invalid or corrupted file

Try deleting your obj and bin directories, and doing a clean build. It is what we have helped to resolve this error in dotnet/runtimelab#1436 (comment)

A better solution is tracked by #79634 .

I deleted many .net 7.0 version folders on the computer and uninstalled it

Manually deleting the .NET 7.0 version folders under C:\Program Files\dotnet corrupts the installation. Repairing the installation using Visual Studio Setup may help in this case.
