On auto sync (like when opening and closing the app) and when I manually try to sync my library I get a vague error. The only odd thing I can think of is that I use one of those “parallel” versions of Ankidroid on my newer tablet since because I couldn’t find a fix for the error it had (see bottom of post). The error window that pops up is incredibly vague, unfortunately. **“Please sync again. If this message keeps appearing, please post on the support site.”** …with no codes or anything to put with it. I’ve tried logging out and back in to sync in preferences. I’ve tried check database and media. I’ve tried uninstalling and reinstalling the PC app with the website link. (Version in About section is: Version ⁨25.02 (038d85b1)⁩) I’ve tried resetting window size. I’ve restarted my computer. I’ve checked my network connection. I use no add-ons anywhere, to my knowledge. OS: Windows 10 Syncing works fine on my phone’s Ankidroid (normal install). Syncing works fine on my tablet’s Ankidroid.A (parallel install thing). Syncing doesn’t work on normal Ankidroid version on my tablet ((java.io.IOexception: fstat failed: ENOENT)). I’m not sure where to pull error codes etc from because I’m not very tech-savvy when it comes to these things, but I’d appreciate the help. 😓 ---

There are similar issues on the thread below, the user there had an empty file that messed up the syncing. > [@Please sync again error endlessly](https://forums.ankiweb.net/t/please-sync-again-error-endlessly/14159): > > Whenever I start anki or try to sync I get a dialog with “Please sync again. If this message keeps appearing, please post on the support site.” I’ve tried; starting with shift held down uninstall/reinstall the latest version (2.1.48) hitting sync endlessly to the same result. Check Database & check media This is on a window laptop if that is relevant. Thanks! ---

I’ve done the debug they did in that thread, but the original poster removed what they got when they executed the import json/print in the debug console. The person helping identified a jpg that wasn’t being saved in the next reply, but output I’m getting in the debug console doesn’t mention any specific files. It gives two file/lines then ends with: NameError: name ‘os’ is not defined. ---

Does anyone have any tips on reading the code or something? I’m not sure what it means and it didn’t seem to list a specific file I could create to fix this problem like in the similar post (which had a missing jpg). ---
