i have a problem
its stay like this if i open yarn i dont know why
Have you tried the built in version of yarn in GD? Basically, select the Load dialogue action, and when it asks you for a file select Create with yarn. This loads yarn in GD without another program running.
he is stay like this for 20min 
It seems like you are using an old version of Yarn. Try updating it and see if that fixes it.
Idk how to update yarn can you tell me
Go to this link:
and install the file that works for your device. In my case (windows) I would pick the .exe file.
If you are on Mac, download the .dmg file. If you are on Linux, download the .snap file.
realy thanks <<<<333
