What issue do you have?

For some weeks already the issue is the sync with a particular file. When I remove this file, the problem persists with a different file.

After removing fives different files, the problem persisted. Is the message from Joplin below:

Does your issue persist after starting over from a JEX backup? Follow this guide: How to fix synchronisation issues and start over

Are you using a free Tab Digital account? The error you are getting is consistent with what others have experienced where Tab Digital has encrypted their data (basically making it unreadable by Joplin). See Unexpected character: H - #18 by mrjo118
