Seems Akonadi tried to execute "INSERT INTO PimItemTable (rev, remoteId, remoteRevision, gid, collectionId, mimeTypeId, datetime, atime, dirty, size) VALUES (:0, :1, :2, :3, :4, :5, :6, :7, :8, :9)"
and gets error "Incorrect datetime value: '2023-02-22T12:00:36Z' for column `akonadi`.`pimitemtable`.`datetime` at row 1" Can you check what the schema for that table is? How does the current data look like? (Unless you are sure the root cause is https://bugreports.qt.io/browse/QTBUG-95071) Or could this be a variant of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993219 ? Very weird that Akonadi would stop working on an upgrade of 1:10.3.38-0+deb10u1. Does it start working if you downgrade back to 1:10.3.37-0+deb10u1?
