What's your disaster plan? I occasinally get stuck with a vault that won't open. Divide and Conquer can be useful to work out which plug in is causing problems. But what if your Community Plugins is blank? Today my vault wouldn't initialise. After trying various measures, I found the most efficient way of starting it was to remove the json file for community plugins in .obsidian. I could then enable the plugins gradually to find the culprit. It turned out to be DB Folder.
