Now i'm experiencing this problem again, I did try uninstall every suspicious fonts. But it seemed crash everytime with every different font. It crashed when I scrolled down font dialogue window to 'L' so I deleted most of chinese characters and korean fonts starting with 'L' and 'M', now it freezes while scrolling 'H' whatever fonts. Really? I have affinity designer, photo, publisher beta on Windows(Korean) 10 system. At early versions of affinity softwares had these problems, but at some point it seemed gone. I'm satisfied with the affinity products and for a while there were no problems with the any asian fonts, but font freezing is coming back again. Designer and photos are both 1.7 now and it's almost impossible to enter any texts and change fonts. Well, I can always use 'Arial' font, but I wonder is there any solution except for removing every fonts in my system.
