This was resolved after a computer reboot, but I'm putting it here for a while to keep an eye on it.
Steps to reproduce:
Start guider GUI ds9
Load custom buttons with guider.ans (as part of startup command or afterward with XPA)
Open new ds9
Close new ds9
Use any custom button —> guider GUI ds9 freezes
