## 6. Observations and Possible Causes

- The crash originates in `libmwinstall_activationwsclientimpl.so` (license activation client).

- The stack trace heavily involves licensing modules (`libmwlmgrimpl.so`, `mwlicensingproductmatlab.so`, `libmwservices.so`).

- The fault likely occurred during license validation or communication with the license server.

- Potential causes:

- Network issues preventing license server access.

- Corrupted or expired license file.

- MATLAB licensing service not running or misconfigured.

- Incompatibility with the system's GLIBC version (2.43) or other libraries.
