LibreOffice Windows x64 Crashes when unattended.

I wanted to see if anyone was having similar issues and if this is something I should file a bug report on or if the problem might reside elsewhere. So I defer to those wiser than I.

Version: 6.3.4.2 (x64)
Build ID: 60da17e045e08f1793c57c00ba83cdfce946d0aa
CPU threads: 16; OS: Windows 10.0; UI render: default; VCL: win;
Locale: en-US (en_US); UI-Language: en-US
Calc: CL

When working on a project I will often save then leave what I am working on open and come back to is later. Such as after diner or such. I don’t have an exact time frame but I’m guessing at around an hour or more. This happens more frequently when using Base, but Writer and Calc have also done the same thing. When I return the program is non responsive and generates the following Windows Event.

do you have any AV or possibly Windows Defender is ON?
Also there is a newer version out. Try installing 6.4.6
