mfxplugin64_hevce_gacc.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mfxplugin64_hevce_gacc.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Vegas Pro 16) could share the same mfxplugin64_hevce_gacc.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when mfxplugin64_hevce_gacc.dll is attempted to be loaded either when Vegas Pro 16 is starting up, or in some cases already running. Some of the most common mfxplugin64_hevce_gacc.dll errors include:
- Access Violation at address - mfxplugin64_hevce_gacc.dll.

Your mfxplugin64_hevce_gacc.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Vegas Pro 16), or deleted by a malware infection.
