This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

Yes, this is possible. Maybe the compiler you have used for the older versions, used UINT32 for addressing and now it is size_t?
There are many ways to kill a C-mex function by an access violoation. Dangling pointers can cause not reproducible crashes also: If some memory is free'd already, it might still have the correct value. But this can change for random reasons. In opposite to Matlab, C and C++ is fragile. If a function does not crash 100'000 times, this is still not a reliable statement if it is free of bugs, which will let it crash in the next call.

Thank u!I‘ll check the C code firstly, and then test the program.’

I had solved this problem, the reason is the error about the input parameter. One of hte program's input parameters should be a complex number, but the input number is double type. So it does not have imaginary part, and caused the crash of matlab.

The last file it mentions before the final gasp and death is "D:\matlab_files\yuhengv2\LLS-NR-pattern\11_demodulation\demod.mexw64". Are you sure that file exists?
