Since a few days, I started to use SponsorBlock which is an awesome script but OSC doesn't show on some videos with this error :

[modernx]

This is the launch command :

Remove sponsorblock.lua from scripts folder solve the error but disable SponsorBlock

How to solve this error and keep SponsorBlock enabled ?
