Factorio Forums

I used to play the game normally. Now it doesn't start. I tried to reinstall graphic cards; run as admin; rename the config file; and didn't have any success.
Please find my log attached. It silent crashes while "building prototypes"

Try verifying the installation through steam. If no issues are found, try the non steam .zip version with default settings.

I did verify it through steam. It passes the verification.
I downloaded the zip version, unpacked, ran. Same issue. No success.

I also tested old versions, like 1.1.110 and 1.1.57 and no success...

Post the log of the latest .zip version, you could also check if there is an os event log. Usually crashing without any log entry suggests that something external is interfering.

The log of the zip version is the same as the steam version.
However I found something interesting. Checking the OS event log, the crash is reported as error in ucrtbase.dll
I searched online and it looks like this can be related to sound driver issue. I reinstalled my soundcard driver, but no success.

I did a test disabling all audio controllers but the one I use and the log went a bit further, but still crashed while "loading sounds"

If I disable them all it still crashes... system log shows the same error for all tries I did...
I tried to run with --disable-audio. The log went further only to crash on the same ucrtbase.dll

Any ideas on that?

???

I'd try replacing that dll file and running the Windows health restore tool.

I tried that and didn't work. Also, looking for the error online it was suggested that might be some issue with VC++, which I uninstalled and reinstalled, without success.
I ran the standalone version, unsuccessfully.
I even upgraded my windows from 10 to 11 to try to solve this...

Reinstall Windows. Or install Linux Mint (20mins).
That's probably easier than trying to debug this for days on end.
