LoadLibrary A.dll failed, and GetLastError returns 193, %1 is not a valid Win32 application.
Maybe the b. DLL associated with a. DLL is not updated, such as a new DLL with a new interface (GetVersion) in the application, and the current B.DLL is not updated, resulting in a 193 error. The dynamically loaded library depends on other dynamic libraries, and you just replace the dynamically loaded library in the library, and the dynamic library dependent library is not updated.

There is also a problem with the 0xc000007b startup program: it is likely that the dependent library is in conflict (that is, the dependent library’s version may not be correct)
