If this is something to do with your vault or plugins, uninstalling the app will not do anything. Because uninstalling the app has no effect on your local vault settings.
Does Obsidian work enough to do anything? Are you able to run “Show debug info” and paste that information in?
Otherwise can you please answer:
I see Obsidian 0.14.6
What installer version? When you reinstalled, did you install from the latest version?
What plugins do you have installed? If you can’t “Show debug info”, go into your /.obsidian/plugins folder and take a screenshot, or list them.
Backup your entire vault first please:
If you are unable to interact inside Obsidian to be able to turn of “safe mode”, you can also try moving your /.obsidian/plugins folder OUT of your vault. Move it somewhere safe. And try to relaunch. Your plugins won’t load, and you might see if one of them was causing the problem.
You can also try moving or deleting (BACKUP FIRST) your entire .obsidian settings folder. You’ll reset to default settings. Then if that fixes it, you can move your backed up settings back in partially, until you find out what is broken.
And just to double check and be clear, did you download and install the latest Obsidian 0.14.6 from the website?
Since this isn’t a vault problem, I don’t know if I can help any more. Sorry.
One other thing you can try. Delete the app settings files here: C:\Users\USERNAME\AppData\Local\Obsidian
Again BACKUP that folder first, just in case.
But I am just guessing. I’m not sure if Obsidian completely refreshes that folder. You can try deleting that data. And then reinstall the app again. Maybe there are some old corrupt settings that don’t get deleted automatically. (I don’t know.)
Does anyone else know? Are there any other settings folders on Windows?
