Unable to load selected layer in TrainVectorClassifier

Hi, I am doing an object classification in QGIS. I have done layer with a tool Join attributes by location. Now I want to use a tool “TranVectorClassifier”.

My system: Windows10
Version of the OTB 8.0.0.

QGIS version 3.6.12

Description of my issue
My problem is: when I choose “joined layer” as Input Vector Data I see a messege: “Unable to load selected layer or table. Dependent field cannot be filled in”. How can I solve that?

Dear @Aldona,

Thank you for using OTB.

OTB is not compatible with QGIS 3.6.12. With OTB 8.0, you need at least QGIS 3.18.
