Hi JimH,
I have already done all the Windows defender settings and dont run a 3rd party AV.
However, today when I fired up MC25 it did not crash! I didnt do anything with it, just left it there, running. As said in my earlier post, it usually crashes out in under 60 seconds. I have made no changes to my computer or MC25.
The only difference, my HTPC was powered on and on the network (also running Windows 10 1903).
I have never connected to that PC in any way, shape or form via either the old version of MC (21) or the new - 25. I have connceted to it via Windows etc. and do have shared drives on it.
By the sounds of it, you have some kind of network stack issue or network auto discovery bug. I have turned off all those options now - perhaps better to have these defaulted to off rather than on (so auto import only works locally on the PC that MC25 is installed on by default) . Looking at my logs from yesterday, I can see MC25 trying to access my HTPC shared drives etc. despite I have never instructed MC25 to do that.
I'll update in due course if turning off all the auto import and auto media server discovery stabilises MC25 when my HTPC is off.
