Thank you, to everybody trying to help.
 
That was very cool bitflipper, I hadn't made my way into the event viewer before.
 
I have included this info from the event viewer, this seems to be a re-occurring theme.
 
Faulting application name: SONARPLT.EXE, version: 22.12.0.12, time stamp: 0x5851888c
Faulting module name: ntdll.dll, version: 10.0.14393.479, time stamp: 0x5825887f


I have been using the UAD plugins for several years without a hitch & there doesn't seem to be any problems there, according to the event viewer.
 
There's over 1,000 application errors & most of the ones that I have read are giving the same sort of info as outlined above.
 
However, I did find a few crashes relating to a Soundtoys plugin 'LittlePrimalTap'.
 
I will be trashing that from the session. 
 
Thanks again, for everybody's input.
