RTL for Arabic font

I have tried to use Shotcut on another old laptop computer with updated Windows 10. The Arabic seems to work fine over this laptop. But on my new computer that I am using and I am having the issue I started this topic I couldn’t. The Shotcut program version is the same on both computers. I have double-checked the regional & language settings in both computers they are the same. There must be a difference between the new laptop windows 10 settings and the old laptop windows settings. Is there a way to find out where the difference is? or which windows 10 update it is?
or maybe someone could have a solution?
