When exactly does the freeze happen? Is it when the file explorer opens? When you navigate to the right folder? When you type in the name of the file? When you hit save?
Also, as what are you trying to export the file?
Does it work when you’re exporting as WAV to your desktop?
Of course the language “shouldn’t” matter, but sometimes it does because Windows uses different input methods to handle multi-byte characters in some languages (such as Japanese).
With regard to the Windows bug that I referred to, that does not matter. The bug is to do with the internal mechanisms that Windows is using for keyboard input. (One of the Audacity developers had lots of “fun” finding the cause of Audacity freezing on Japanese Windows - the only way he could reproduce it was to install Windows in Japanese, which is not easy for someone that does not speak Japanese.)
