@SophieLopez - Sorry that you’re having this issue.
Depthkit.js is now a community-maintained project, and has been a challenge to maintain while updates to underlying libraries and dependencies cause the integration to break, as has been seen within other forum threads.
This is one reason why we are moving our web player integration toward streaming mesh sequences for both Depthkit Core and Depthkit Studio captures. You can see a preview of this web integration in action in this post from @Tim’s LinkedIn: Depthkit 1st Party Web Player Preview . Support for this format will be available in the next Depthkit release in the coming weeks.
