Stuck in infinite loading screen

With dev tools:

Open and be able to view notes.
Just started happening one day. Storage is in Dropbox, but I reinstalled so it shouldn't even be connected to those.
In the dev tools I saw that it was still using the storage in Dropbox, but I was able to delete it. Now I can get into the "Create Storage" page. I moved the storage out of Dropbox and into my documents, but I'm still getting the same error.

Transferred this to the correct repo
For anyone else with this problem, I wrote a quick python script to remove the notes since I needed them immediately. It only takes title and content, and sorts them into their respective folders.

I've had the same Problem. In my Filesystemstorage i had a Folder /notes/notes and a file
notes/boostnote.json with following content:
{
"folders": [],
"version": "1.0"
}
I deleted this file and the folder and restartet Boost Note.app. Now Everything works fine again.
Error started with upgrading form 0.10.1 to 0.10.2.
I got this exact problem. I moved the local storage folder and then restarted Boost Note, and it booted without a problem. I then manually copied the folder info from the old boostnote.json to the new boostnote.json and also copied over all my notes-json-files folder by folder. When I came to the last file in the last folder, Boost Note was back to this infinite loading.
I then remembered that I had tried to make a tag called constructor in that last note, and it didn't work for some reason. I checked the old boostnote.json, and it didn't have a constructor-tag, but the note file I had tried to make the tag in had a tag called constructor. I removed it manually from the note json file and Boost Note then booted with no problem again.
I then added the tag manually to the new boostnote.json. Still no problem booting. Went on to manually add it to the note json again, still no probs. The tag is there in the tag list. I added the tag to another note through the program, no problem.
I find this last part extra weird, since the new boostnote.json updated with tag-names automatically when I moved a note with tags to the correct local storage folder. I only wrote in the folder info manually, not the tags. So instead of just updating boostnote.json with the constructor-tag (along with the other tags in that note file), everything crashed...
Someone knows what happened here?
