Thanks for the log files.
You are running the 32-bit version of Plex Media Server. Notice (a) the build is -x86, not -x86_64, and (b) the install location.

PMS is hitting a Windows resource limitation. This message repeats several hundred times before the system crashes (at the end of Plex Media Server.1.log).

Suggestion: Download the 64-bit version from plex.tv and perform a manual install (link).
I searched the forum for “Couldn’t add a new thread.” There were several reports, and all were running the 32-bit version of PMS. Updating to the 64-bit version of PMS resolved the problem.
You can install the 64-bit version on top of the 32-bit version. The installer will remove the old version.
Before updating:
You are running PMS v1.32.7.7621. The current public release is 1.40.2.8395.
PMS 1.40 introduced many database changes.
You may see a “503 maintenance” message after installing the PMS update.
If so, wait. It will take Plex some time to update the database to the new format. The amount of time depends on the size of the database and the speed of your system. For some, it takes minutes, others have reported hours (ex: PMS on Celeron based systems).
Do not stop PMS. Doing so only delays things. The database migration process will restart when PMS is restarted.
Do not try to downgrade. This risks database corruption.
Check on the system every 15 minutes or so. The “503 maintenance” message does not auto update. You will need to refresh the browser window (or close & re-open).
FYI 1: A side benefit of updating to 64-bit PMS is more efficient transcoding and hardware accelerated HDR to SDR tone mapping when using the Nvidia GPU. Specifically select the Nvidia GPU in Settings → Transcoder instead of leaving it at Auto.
FYI 2: PMS 64-bit has been available since Sept. 2022. However, the Plex installer does not mention that a 64-bit version was available (resolved in current beta). So, if you installed PMS before that date, you were never informed that a 64-bit version was available.
