Hi Bro,
To make things more confusing, in reaction of your fourth point concerning "Unrecognised database format ...".
We experienced this error in different situations. At first it was as you say, one user was blocked by it while other users could work with the application. If the user waited long enough he/she could work again without being blocked by this error.
An other issue we had was that from within the application data was written to another backend. In november 2019 it looked like almost every user got this error when using this function, but not all users! I worked around this problem by importing the tables into the main backend. The only thing here is that the backend has become large (> 500MB).
Last week I had to do some analyzing on the database and had made a couple of queries. They ran fine but at some point when I wanted to requery them the "Unrecognized database ..." error popped up. This was all in the same session. I closed all of the queries, builded them again, ran them and no errors...
Not very helpful but perhaps someone else can relate and possibly share an insight?
