Fatal Error: "Unknown profile version" - 20240303

As I said it earlier:

What I attempted to do but not yet:
I am thinking to restore the setting from Joplin Backup plugin restoration, but I am not sure if this is a good idea.

So..., during the process of searching for a solution of the main problem of this thread, I spent some time and took a look at how things go when one try to restore his/her notes from Joplgin Backup plugin file, I created a new Joplin profile in a new Windows user account and then import my Joplin Backup plugin file, and it works fine and took only some time within 30 minutes. Except I am not sure what will happen if I sync the restored profile with my Dropbox sync file. Will all the notes becomes double or what? This is one thing that I am concerning, I just had a quick search in Joplin forum and something not very pleasant come to my eyeball.

@JackGruber

I don't think this will work.
If I am correct, new IDs are assigned during import, so every note and the resources would be available twice on the sync target.

So now I am taking a second look to the worse case scenario as below:

@KC_20CY

What concern me in one of the worse cases:
I am concerned that one of the worse case is that I need to sync everything back to local from Joplin/Dropbox cloud file, I have more than 25000 notes, the first time I synced from local to cloud took days, a waste of lots of time really concerns me.

I am still looking forward a easy way out of this rabbit hole.
