All I can say is that this error messages comes from Spatialite that can only 
handle 64 connections in a process at most. I did a fix (don't remember when, 
but must be included in QGIS 3.4) in the QGIS OGR provider to be able to open 
GeoPackage datasets (since the OGR GeoPackage driver enables Spatialite on 
them) that has many layers (so that they share the same connection). Not sure 
about the specificities of your use case.
