[RADIUS] Can i crack a MS-CHAP2 with known shared secret

[rdk95]

Hello I wanna do a pen test on my MikroTik devices because they are getting hacked
the hacker is getting my radius accounts [Free Radius]

I've tried to capture a session with me logging on one of the MikroTik Devices

and i got this output
the following link can be opened via wireshark

shared secret key is : qM0jU1iQ9oI


i can see my username through the packets capture
MS-CHAP-Challenge: e012ac3cc4117fc273eca39b3a911726
MS-MPPE-Recv-Key:
MS-CHAP2-Success:

Is there any way to decrypt these with the shared key

Thanks in advance for any useful idea or explanation
