RDP Relay session capture not working with PAM 3.6

Hello,
when configuring the rule of RDP RELAY with PAM 3.6 , when selecting the session capture the RDP was not working,
when deselecting the session capture everything was fine,
after troubleshooting in the packages on the target agent the rexec module was installed registered but offline so the error in logs was:
Error, NPUM driver is not initialized. Try restarting NPUM service or system restart.
Error, Failed to load module rexec: Unknown error
however i did the restart of the target agent machine with no success,
Thank you in advance,
Regards,
Elias
