Flex 6500 crashing with Elecraft KPA/KAT 500 on 6 and 20 meters

I posted a few days ago about issues with my Flex 6500 / KPA/KAT 500 combo. Thank you for the feedback!! The original issue has been resolved - but now a new one has popped up.
I work primarily digital - when I try to transmit using the KPA 500 on 6 or 20 meters, SmartSDR will freeze - then the error message indicating the computer is no longer communicating with the SDR comes up. The radio does a self-reset, then I can activate the system again.
Yesterday, I completely removed SmartSDR from my system. Reset the Flex to factory. Then, reinstalled SmartSDR. Removed and reinstalled all my COM ports. I also added ferrite beads to all of my lines (I know that all of them did not need it, but it was a hail Mary). My antenna is a GAP Titan. SWR for 20 is 1:1.2, for 6 it is 1:1.5.
Everything was working on all bands on New Years Eve and Day. On the 2nd or 3rd, there was a Windows 10 push update. An another one yesterday - on the 8th.
Has anybody else run into this issue? Does this sound familiar at all?
Any comments / assistance is greatly appreciated!!

Turn the power down to one watt and see if it still freezes, if not, keep increasing the power until you see the freeze. In that case, its R.F. getting into your router or Ethernet, otherwise Jay can be very helpful.0

That's been my issue here as it seems if I moved-added-re-arranged sneezed RFi sneaks in some where with computer acting funky.
It has always been Rfi =more toroids/beads added somewhere.
Nature of SDR and with computers added to the rfi-blending in.
Great Advice Doug!

I had a similar problem and found that the Ethernet switch was locking up that my computer and flex were plugged into0

Same here. RF (CMI) on usb and Ethernet cables causes all kinds of strange behaviors. Some well placed chokes on USB, Ethernet and power cables solved it for me.0

I use mfj 915 isolators on the output of the kpa500 which feeds the tuner next in line never had rf issues with router computer or software lockups and none of my equipment shares common grounds either, it just all works great! Just lucky I guess.0

We can fix that! Just experiment more hihihi0
