Hi @yanak17669322 I'm sorry to hear about the problems. It sounds as though you've tried several of the recommended fixes already. Which version are you using? The most recent is 23.5.1. If you roll back to a previous version, does it happen? Did you reset Photoshop's Preferences? If permissions are set to Read & Write, try changing the directory ownership (and/or create a new user). Did you try exporting after completely quitting and signing out of Dropbox, instead of only pausing? Also, does this error happen only with the one GIF file you're trying to export? Can you export correctly using Export > Save for Web (Legacy) for all other types of files and formats? With a different GIF file? Any more info you can give about your system specs will help, too.
