When you try to glone them with this manual
You'll most likely see that the step of resolving delta's is taking it sweet time. I asked support to fix this issue for me. But then it suddenly stopped for me....
But now its coming back - i can confirm with you its not a connection or laptop element on it but it is related to Mendix and/or GIT.
If you are seeing this issue on multiple versions of Studio Pro, it would suggest the issue is with your computer or network connection.
There are a few things you can try.
Good luck!
