It seems that this game https://play.cprewritten.net/2020/ doesn’t load correctly when shields is up. It blocks this https://browser.sentry-cdn.com/5.19.2/bundle.min.js?_=1609766452234
which I don’t know if it’s an ad or something needed for the game to load correctly, so you can exclude it from blocking.
Soon the game will be playable under this url https://play.cprewritten.net/
Update: It seems to work if you change to “Allow all fingerprinting”
