Using the CV turns off Pyramid

Hi I was wondering if anyone else has this issue: so to start I updated to the newest ver of the OS (3.22) using the MKI of the Pyramid and for some reason everytime I enable CV mode and plug the outputs into my modular, the unit shuts down. If I have the unit plugged into the modular before powering on, the unit will not turn on. I really cant understand why the unit is acting that way so if someone can give me pointers thatd be great. thanks

How are you powering the Pyramid? Via power supply or via USB power?

power supply

Sorry. That was the only thing i could think of.

what voltage is on the CV? or maybe the pyramid doesn’t like when the CV input is shorted? or maybe the pyramid PSU ground and your modular ground have some noise between them?
