    I solved this issues that copy from other pc's windows fonts folder, and pasted it to my pc.

    A fix for this issue landed in Unity 2022.2.a1 which should be available soon. This fix will be backported to previous versions of Unity but has not landed yet.

    In terms of the issue, it is caused by a system font file that has no font family or style name which makes this font file invalid as all font files should have a family and style name. Ie. kind of strange to spend hours designing a font but to not give it a name ;)

    A potential short term solution would be to look through the installed / system font files on your system(s) to identify this font file and remove it.

    P.S. I would love to get my hands on such font file as I have not been able to find one. It is not possible to create such font file as font editing tools have safeguards / prevent font files from being created without a family or style name. Had to binary edit a font file to replicate this ;)

    Is it possible to workaround by installing a font? Is there any way to know what font is missing?
