I fear you may be suffering from the same issue as in the post you linked. The issue is on the devs radar but with no reliable way to reproduce it they are having a hard time narrowing down the problem. I will forward this post on to them to add to the list of evidence.

Can you share your logs.zip file found in %UserProfile%\Zomboid?

Can you try increasing the RAM allocation for the game? Go to the install directory, edit the "ProjectZomboid64.json" file and change the line "-Xmx3072m" to "-Xmx6g" instead and see if it helps?

You would need to replicated it with no mods enabled before it can be confirmed as a game bug.

Can you try the steps below to repair any corruption in the ntdll library? Press the Windows Key + S and type cmd. Right-click Command Prompt and select Run as administrator. Type sfc /scannow and press Enter (wait for the scan to finish). Afterward, type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter. Restart your PC once both scans are complete
