I'm sorry. My English isn’t that good.
I’m still practicing.
I use Google Chrome v.80.0.3987.149

Go to your project settings -> Advanced and deselect Use worker.

but I can do it because of you
Thank you so much :)

Develop games in your browser. Powerful, performant & highly capable.
oh...I got it
Thank you so much.
Another note, now you can call alert() in worker mode in the new C3 beta release!
See the scripting section of the above post for how to do it (and thanks to Ashley for adding this support!)
