6.39rc38 crashes using superchannels

Since i updated my Metal 2 on the Station side it crashes when using superchannels mode.
On the AP-side the same firmware does not crash using superchannels.
Can anyone confirm that issue?

(Reverted to an older firmware version and superchannels work normally again)

please send the support output file form the crash to support@mikrotik.com

Since i gone back to an older firmware version i can not generate a support output file.
