The error message indicates that there is an unresolved error code 0x80040266 when trying to render the DirectShow player service. This could be caused by a number of issues such as incorrect installation or configuration of DirectShow, missing codecs or filters, outdated drivers, etc.
Here are some steps you can try to resolve this issue:
Check if all the required DirectShow components are installed and configured correctly. You may need to reinstall them or update them if they are outdated.
Make sure that all the necessary codecs and filters are installed on your system. You can use third-party tools such as CodecInstaller or GSpot to check for missing codecs and install them.
