CW Keyer & CAT control together for just ONE minute??

[sm0ikc]

Hi,
I´m using LOG4OM2 with a IC-7300. CAT control via USB and OmniRig.
The IC-7300 is on COM8 and I use a VSP port splitter to obtain two (or more) virtual COM ports in order to be able to use the Log4OM Keyer interface. Virtual COM1 is used by OmniRig and virtual COM3 is used by Keyer interface (Keyer engine: Serial port).

It works, sort of... for one minute.
The Log4OM CAT control can run together with Keyer interface for approximately one minute, then CAT goes offline. Why??!
I figure if CW keyer and CAT can run simultaneously for one minute they should be good to go for unlimited?
I attach some setup screenshots and a link to a short YouTube video where you can see it for yourself.

How can I make CAT and CW keyer co-exist over unlimited time, please?
