nRFgo STudio crashes when app starts

[Gray]

When starting nRFgo studio it crashes instantly. I have tried uninstalling it several times. It appears to install correctly including all the J-xxx components, but will not start without reporting an unhandled exception See Unhandled exception at 0x6b607a05 in nRFgoStudio.exe: 0xC0000005: Access violation reading location 0xc5c5d6ec.

Can you advise how to get the app installed.

I am using windows 10Pro 64 bit computer

It is the 64 bit variant of Studio I am installing I have uploaded the log file as requested log.txt

I have uninstalled a number of times including uninstalling the J_** set of software. I do have it working on my MS surface, but the development machine is where I really want the SW to work. This includes deleting all the directories. I did not go into the registry to try to detangle this though.
