widevinecdm.dll keeps on crashing with the error EXCEPTION_STACK_BUFFER_OVERRUN / FAST_FAIL_CONTROL_INVALID_RETURN_ADDRESS
Hello,
I’m experiencing consistent crashes of the plugin widevinecdm.dll whenever I try to play DRM-protected content (for example, streaming platforms that use Widevine). Every time playback starts, Firefox crashes and the crash reports show errors related to widevinecdm.dll, specifically: EXCEPTION_STACK_BUFFER_OVERRUN FAST_FAIL_CONTROL_INVALID_RETURN_ADDRESS.
In such instances, Firefox keeps working normally. The tab doesn't even crash, it's just the player not responding and the message above telling me that the plugin has crashed. I have already sent multiple crash reports, the last one you can find it here on the Mozilla Crash Stats platform.
Does anyone know how this can be solved? I literally cannot use any subscription service anymore.
