Problem with proj.db

Hi. I got a question about the usage of OTB in QGIS (version 3.16).
When I try to use algorithms such as ComputeImageStatistics, TrainImageClassifier, ImageClassifier, I see message:
ERROR 1: PROJ: proj_identify: Cannot find proj.db
I tried to use versions of OTB, such as 3.2.0 and 3.4.0, but every time I got this message.

Dear @slavavaliev,
Thank you for using OTB.
Does this thread help you in solving your problem ?
