Explorer Crash during Plex Server Scheduled Tasks which also affects PlexHTPC

Server Version#:1.42.1.10060
Player Version#: PlexHTPC 1.71.1.346

Hello all

Occasionally, Explorer.exe Crashes overnight, always between 02:00 and 05:00.

These Times are specifically when Plex Server performs its Scheduled Tasks.

I have nothing that Runs overnight, except for Plex Server.

I have been trying to Troubleshoot the Issue which has been difficult as it does not always happen.

Last Night, it did.

This is the Error from Event Viewer:

When this Error occurs, Explorer Crashes and PlexHTPC just shows a Black Screen, pressing F5 to Refresh the UI does nothing and the only way to get PlexHTPC working again is to Restart it.

Also, this Issue Never happens during the Day.

These are the Plex HTPC Logs from Last Night:

Has anyone experienced this Issue?

Thanks in advance

Hello all

Just a Quick Update.

Adding an Exclusion for the Plex HTPC and Plex Server Program Directories to Windows Security seems to have Solved this Issue.

It has now been over a Week since I Added the Exclusions and I have not had a Single Crash since.

Hopefully this Issue is now Solved.

Thanks

Kevin
