while loadlibrary error in latest version

After I upgraded my MATLAB version from the early 2024b release to the latest version, the .m files that I could load normally before started to have issues. They worked fine in both 2023a and the early 2024b release, and my code hasn't changed at all. However, they fail to run in both the latest 2024b version and the 2025 version. What could be the reason for this? I hope to get help as soon as possible.

Submit this to Mathworks as an official support request/bug at <Product Support Page>. If you can't call the US number, there's a link to local distributors at bottom of page. You will need to follow the directions about preparing sample cases that cause the problem.

The Answers forum is not an official Mathworks support site and without example code to try to reproduce the problem, there's nothing folks here can really do.
