JK crashes (Not Responding) every time I try to connect to any session

I was playing with my bandmates for about two months then… JK pushed an update a few weeks ago now JK crashes (Not Responding) every time I try to connect to any session. 
I have a Lenovo Thinkstation workstation class computer with an Intel  Xeon ES-1630 v3 3.7 GHZ  Quad Core CPU – 48 GB of RAM – SSD RAID 10 drive array – latest version of Windows 10 Pro OS 64 Bit OS and a Nvidia P6000 Video card.  My network router is a Synology AC 2600 and a 1GB PakEdge switch.  My internet connection is 600 down and 40 up with a Static IP address from Spectrum.  Additionally, I am using a Logitec Meetup Video Teleconferencing box for video.
I have tried everything I can think of.  I uninstalled JK and deleted all the leftover files and installed a fresh install.  I checked for updates. I tried 3 different interfaces.  A Steinberg UR-44 II, a Zoom UAC-2 (USB-3) and a Roland Quad Capture.  They all yield the same results.  
JK completes the media relay server search process successfully every time.
Additionally, I tried my Laptop.  Lenovo Thinkstation workstation class laptop with similar specs and it does the exact same thing.  Crashes (Not Responding) when I try to connect to a session.
Anyone have any ideas?

I had a worse problem when I came from Jamulus back to JamKazam with my Focusrite Scarlett 2i2. Jamulus had set the Buffer Size to 136 from 120. I had to go into audio gear and then configure which was enough to get JamKazam to reset buffer size to 120. With buffer size at 136, I got the blue screen and the computer rebooted when I tried to join a session in JamKazam. Could be a similar problem with you.

Same issue here. MacBook Pro 13" with a quadcore running Catalina. Updated prior to starting a session and everytime I tried to open a session of any kind JK immediately crashed. Has anyone heard anything at all about a reason or solution?

Mac users (Windows too?) can create a log
in JK client, before attempting to join a session, go to Manage/Support/Log
this will show the console - you may find logs from JK already there
If the client crashes again, at least you will have a log to help figure it out

Can you tell us what version of the JK client you are running? Manage/About...
