Unable to connect to oracle DB from Biztalk send port from Biztalk 2020 prod server

Question

I have installed Biztalk 2020 and installed the 64 bit. All the installation is done and working. Last i want to send message to Oracle DB, i am using the biztalk send port to send this message. When sending the messge i am getting below error: "

System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=4.122.19.1, Culture=neutral, PublicKeyToken=89b483f429c47342'. This assembly was compiled for a different processor.

I have installed Oracle ODAC 12/18.3 version to make sure i have the latest dll.

In machine config i have configured with the latest dll. But still i am getting an error

When i am creating the Oracle sendport i am getting this error, i am not sure where to update the config to support 19.1 version.

Please advice , we need to move to prod this weekend.
