From that logfile, you should have several recordings in "D:/Games and stuff/" directory, with filenames like "2021-01-24 03-16-47.mkv". These are your recordings. They may not appear to be video files as Windows' default video handling is pretty bad. They should show up properly if you download and install VLC, a free and open source video player that's much better than the default "TV and Movies" application that Windows ships with.
