I’ve been plagued by the same issue for the last month.
What’s weird is it only affected my laptop (win 11) and not my desktop (win 10).
Based on the recommendations here and my own testing, I think it’s a stale cache within the Roaming folder that was the culprit.
Here’s what I did to fix it for me:
- Win + R to open the run box
- Type in %appdata% and press enter (this takes you to the ‘Roaming’ folder)
- Go into the Obsidian folder and either delete the Cache folder or rename it to OLD_Cache.
- Start Obsidian and see if the cache is recreated and error message goes away.
- If fixed, you can delete the OLD_Cache folder.
For me that solved it. And this was really annoying.
So, I don’t think you have to delete the entire roaming folder and reinstall Obsidian. Best to everyone else.
