Compiler Error Message: CS0009 - mscorlib.dll - asp.net

When I try to run my web application, the following error occurs:
Description: An error occurred during the compilation of a resource
required to service this request. Please review the following specific
error details and modify your source code appropriately.
Compiler Error Message: CS0009: Metadata file
'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' could not
be opened -- 'File is corrupt.'
It seems to me that the .NET framework 4 installation is corrupt, but I am using Windows 8.1, and I'm not sure how to repair this, as it is integrated into the Windows installation.

I manually copied the corrupted file from a different computer with the same Windows installation. It took some permission changing, but I managed to do it.

ALINK : error AL1019: Metadata failure while creating assembly -- The file or directory is corrupted and unreadable

I have an asp.net webform project that build on system1 but not on system2 (they both are windows 10 and visual studio 2022 Version 17.4.3) and when I build visual studio show an error in error list window :
"Severity Code Description Project File Line Suppression State
Error Metadata failure while creating assembly -- The file or directory is corrupted and unreadable. Modabber D:\BehsamanCode\Modabber\Modabber.Web\ALINK"
Also it shows this error in the output window :
"ALINK : error AL1019: Metadata failure while creating assembly -- The file or directory is corrupted and unreadable"
I searched these errors and I enabled long path on windows10 and uncheck Sign the assembly but not work.
What should we do?
I don't know how but it resolved. I think system2 hard drive has a problem and after win10 repair it itself then restart windows the problem gone and project builded.

yes its not a good answer but it was all experience i had with this error.

System.TypeLoadException: Could not resolve type with token 0100000f

I get this error running a sample asp.net 5 application on ubuntu 14.04LTS.
after a successful dnu restore command, running dnx kestrel command returns the following error: System.TypeLoadException: Could not resolve type with token 0100000f.
I tried different versions of mono still the same error. I noticed also a difference between kestrel versions in my project.lock.json file(could it be it).
on the browser it returned an internal server error!
I can post the file if needed.
appreciate it!
