    Description

      Install mutiple font PingFang in operate system, the app will crash by stack overflow.

      It seems like cross call EnumFontFamiliesEx with different font but has same tag, then exhaust stack.The familyName‘s value set to "蘋方-簡","PingFang SC" alternately.

      Qt 5.12.5 runs well, but 5.15.6 & 5.15.9 both failed.

      The fonts can find in attachment.

      Call stack :
