Photoshop supports an extensive range of languages. According to Wikipedia, Photoshop is available in 26 different languages. For the Creative Cloud desktop app itself, supported languages include Brazilian Portuguese, Simplified Chinese, Traditional Chinese, Czech, Danish, Dutch, English, Finnish, French, German, Italian, Japanese, Korean, Norwegian, Polish, Russian, Spanish, Swedish, and Turkish. Adobe has also recently added Vietnamese and Indonesian to the desktop version.
If you accidentally switch Photoshop to a language you cannot read, you can force it back to English without reinstalling. Navigate to your Locales/[Your_Language_Folder]/Support Files/ directory and locate the file named tw10428_FS_win.dat (on Windows) or similar. Changing the file extension to .bak will force Photoshop to default back to its native English interface upon the next boot. Conclusion
Open Photoshop and go to (Windows) or Photoshop > Settings > Interface (macOS).
If you are looking to download specific language versions, I can guide you through the process for English or other common languages. Just let me know which you need.
