Creating a new Vlan took down my switch stack

We were trying to add a new vlan to all of our switch stacks (we have about 8 stacks) and everything was going fine until we got to one stack of Cisco 3850s running ios-xe version 16.3.6, once the vlan was added (simply conf t ,vlan 60, name VDI, end) the stack started acting very strange, show run would lock up the session, any commands referencing vlans would also lock up the session, and eventually (about 15-20 minutes later) the stack dropped all connections, and were were forced to reboot the stack. I have been unable to find anything online as to others running into a similar issue as this, but this is also not the first time this has happened to this stack (vlan 110 was the other incident). Does anyone have any clues as to what might be causing this to occur? (edit) We have done all of the troubleshooting that we know how to do to try and discover why this occurred, we did notice a spike in CPU usage just prior to the crash, but were unable to determine what caused it
