Igor Babaev 4de32015be MDEV-21356 ERROR 1032 Can't find record when running simple, single-table query ...

This bug could happen when both optimizer switches 'mrr' and 'mrr_sort_keys'
are enabled and the optimizer decided to use a rowid filter when
accessing an InnoDB table by a secondary key. With the above setting
any access by a secondary is converted to the rndpos access. In InnoDB the
rndpos access uses the primary key.
Currently usage of a rowid filter within InnoDB engine is not supported
if the table is accessed by the primary key.

Do not use pushed rowid filter if the table is accessed actually by the
primary key. Use the rowid filter outside the egine code instead.
