I can't Create font,please help me

I can’t create a font. I Drag my A-Z into fontself but Not show the same My A-Z and see in this image ''Refreshing Font" ???
I restart my laptop is the same result

Hello,
this is strange. Normally you see your font immediately in the Fontself window, like in my example.

If you click on the three strings at the top, you can invoke the “Reload Extension” command in the pop-up menu.

Thank you very much. Fixed it!
