Adobe Audition 24 not exporting audio file to Premiere Pro 24

After upgrading to Adobe version 24. I could not export audio from Adobe Audition v24 to Premiere Pro (v24). I can opened Export to Adobe Premiere but the check box "Open in Premiere Pro" is greyed out (disabled).
I still can use "Edit in Adobe Audition" from Premiere Pro but can't open back in Premiere Pro from Audition.
Any idea what is the issue here? Need help ASAP.
