There's no such thing as a new version of the bglmanx65.dll, the current version hasn't changed since last September, and you can have proof of this by checking the executable Digital Signature, which dates September 14, 2022.
Of course, I check it now, and there's are no issues, using the latest P3D V5.4. Since there hasn't been any updates to the file you think it's the cause of the crash, it's clear it cannot be the cause of the crash but, most likely, the simulator crashed for other reasons, and brought down GSX and all its modules with it.
