Yup, Other programs illustrator and notepad also shows all the fonts I installed.
I checked first that why Designer has an issue like this, then I checked other product(photo, publisher) as well and found the same issue. (fonts are not showing)
I don't know why but it also affects the performance of Designer. (only for 2 - 3 times then work smoothly).
I don't mind using a different font similar to original, but if someone like me uses this many fonts then yes sometimes fonts might not load in software I understand that.
But to solve that issue I reset font in Designer but nothing happens, the result is the same every time.
