I could not find the original, but having a similar issue with this save around 3 November or a few days after save starts.Hello!
I was not able to reproduce the CTD on our current internal build (might be fixed there?).
Please attach the related CTD folder here so I can check on it in more detail.
CTD folders are usually found at:
C:\Users\[USERNAME]\Documents\Paradox Interactive\Victoria 3\crashes
Unfortunately these are macOS machines - DxDiag obviously does not exist since that involves DirectX, a Windows - specific program. Minidumps also do not exist.Without a minidump (found in Documents/Paradox Interactive/Victoria 3/crashes) and a DxDiag log we cannot troubleshoot the CTD, though I suspect you might not have sufficient virtual memory assigned with just 8GB of RAM available.
I'll move the thread to our Technical Support so they might assist you further.
