Error occured while adding a song in a playlist

[Damaskox]

BeatSaber Version 1.39.1
PlaylistManager version: 1.7.3 (according to BSManager)

I receive an error when trying to add a song in a playlist, maybe 2/3 of game boots when I try to do so.
I may need to reboot the game 1-4 times to get it work.
Is a bit frustrating 😅

Rebooting BSManager seems to be a better solution at the first attempt, but it's not a permanent fix.
