As said in error message:

C:\WINDOWS\Fonts: Файл или папка повреждены. Чтение невозможно.

This isn't a JOSM problem, please update your version of Java, make sure Windows is up-to-date, that you didn't do anything fancy in this folder. Maybe you need to uninstall custom fonts, or run a Windows troubleshoot program.

The best we can do is to ignore the error but you risk to face strange font issues.

fix #16646 - catch DirectoryIteratorException when loading Fonts on Windows
