It is weird that Obsidian cannot open itself but only stay in the taskbar. I have tried to reinstall the app to the latest version but there is no work done.
Does anyone have the same issue or may have any solution for this?
In your Vault’s folder, show hidden files, make a backup of .obsidian, and then try deleting it. (No content is in that folder—it contains metadata, such as the current layout of your panes.)
Relaunch Obsidian (and open the problem vault if necessary.)
