Thanks for the updated log files.
Two issues: Nvidia drivers are out of date and incorrect media organization.
Nvidia Drivers
You need to update your Nvidia drivers for hardware accelerated encoding to function correctly:

Media Naming & Organization
You got lucky. Your naming is not close to Plex standards, and Plex is very picky with TV shows.
Your incorrect naming and organization for Good Girls:
Jun 29, 2021 11:00:54.789 [6548] DEBUG - Updating part with ID=149609 [Z:\Serier\Good Girls\Season 4\Good.Girls.S04E09.1080p.WEB.h264-GOSSIP\Good.Girls.S04E09.1080p.WEB.h264-GOSSIP.mkv
Plex does not support subfolders for each episode (…show_name\season xx\subfolder\episode).
You should reorganize your media per Plex requirements. Spending the time up front to correctly name & organize media pays off in the long run.
Step 1: Rename Good Girls to conform with Plex requirements. The entire show, not just the troublesome episodes.
Step 2: Plex Dance the entire show. This clears bad information out of the Plex database.
Note: If you’ve many seasons/episodes, you can do a partial rename to test things, a partial Plex Dance if you will. Follow the Plex Dance steps. When you get to step 5, name and organize one season per Plex requirements, then put just that one season back into the library. Once you have things working, you can then proceed with the remainder of the show.
I could find no references to Lansky in the log files. However, the same comment holds for movies: name and organize them correctly.
