I managed to fix it, I hope by Kawaii at 12:28 PM EST on February 18, 2012
It's something to do with it scanning the library, when you have huuuuuuge media libraries, and folders that have a plethora of different files in them, or something like that. If, in your library settings you set it to include only "legit" audio files, like mp3 flac and ape, the library won't try to scan for all the other game files, I've been running it with the library on, with the include only, and it worked just fine for an hour. I hope this helps anyone, I found this thread because I had the same problem, I just new it had to be in the media scanner, the crash dumps say so.
Now I have a problem by Katsur at 9:11 PM EST on December 25, 2023
My Foobar2000 v2.1 Stable version crashes after installing VGMStream component version r1896. It started with my failed attempts at playing TXTP files of Race Driver: GRID music. Now, even trying to play MP3 files, it keeps crashing.
