Stripe blocking main thread (Google page insights is saying my website is slow)

Hello everyone,

Does anyone understand what this means? Is it just a result of ghosts normal functioning? I don’t use any of Stripes payment features but I suppose it is running because I have members and a mailing list.

What are general things that can be done to improve page speeds as well?

Did you find your way ?

I don’t know, it’s been so long, I have new problems now!
