My matlab fails to start. Assertion failed error message.

I am getting the following error while trying tom open MATLAB (2019b version 3, OS: Windows 10 Professional)

Assertion failed! 
Program: E:\MATLAB\R2019b\bin\win64\libmwfl.dll 
File: b:\matlab\src\mvm\detail\mvmlocalboundmethods.cppLine: 114

Expression: Failed to open local mvm library:
E:\MATIA13\112019b\bin\win64\MVMLocal.dll is not a valid Win32 application.

For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts

Actually I had to reinstall MATLAB, but this might sove the issue.

I met the same problem and solved it successfully!

I found that this file (libmwfl.dll)was deleted by anti-virus software. After it was recovered, MATLAB(2020a and 2023a) can be opened.

Hope my answer might help you!
