Plex crashed multiple times a day Exception Code 0xc0000409

Plex Media Server Plex Pass Betas

Server Version#: 1.41.5.9522
Player Version#:
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Host Server:
Windows 2019 Server
Processor - 13th Gen Intel Core i9-13900k 3GHz
128 GB RAM

All updates to Windows server has been applied as of 3/9/2025

I have isolated the server from all other applications besides Plex Media Server.

This error message happens frequently and the end result is plex media server.exe stops running on Task Manager. All other open Plex EXE files are left running. I either have to end task on all the PLEX related EXE files in Task Manager and then restart PLEX again. This will get it working for a bit.

Actions Taken:

  • Tried a simple reboot
  • Downloaded the latest PLEX Beta and tried to reinstall.
  • Removed AV program ESET to see if there is a change of behavior

All actions that I have taken seem to have no changes of behavior and the Plex Media Server.exe file keeps crashing with the same Event error message.

Error in the Event log is below:

I have tried backing down the version of Plex and still have the same problem. Plex crashes a few minutes after start. Part of me wonders if my database for my collection is to large.

The next thing I have tried is to go into the Plex install directory and changed the properties on all my exe for Plex media server exe and others, to run in windows 8 compatibility mode. Looking for a change of behavior

Problem resolved. Windows Cumulative update. Opened a case with Microsoft and we have solved it. I am little disappointed that I did not get a single response from someone working with Plex.
