[QGIS-Developer] QGIS freezes for minutes when updated SpatiaLite SQL Layer

[SIGéal]

Hi list,

QGIS 3.22/3.24 freezes with hourglass for about 2 minutes when I click 
on close button of Update SQL Layer dialog, even if I didn't modify the 
query.
If I click on Execute button, I get this error : "an error occurred 
while opening GPKG dbname=..."
This happens with a big database file (600 Mb), only with with query 
returning hundreds of rows.

I don't have any problem at all with old behaviour on QGIS 3.16.16 : DB 
Manager opened when I click on Update SQL Layer.
So this sounds clearly like a regression linked to the new "Update SQL 
Layer" dialog/behaviour.

Thanks for any hint or work around,
