If MaximDL is holding up the driver from closing down, you need to have the script disconnect Maxim from the mount. The script could do this first, then allow Maxim to continue running, warming up the camera.

I don’t know if Bob Denny or one of ACP’s users created that script, so if the script author doesn’t know how to disconnect MaximDL from the camera, I believe Maxim’s TelescopeConnected property controls the connection to the mount. Setting this property to False should disconnect Maxim from the scope. For reference, here is a screenshot of the TelescopeConnected property in Maxim’s documentation:
