Windows Calculator application crashes due to WerFault inconsistency when launched from a service using CreateProcessAsUserW()

The Windows service is written in Go and trying to create a calculator in the user context using CreateProcessAsUserW() process.

Its code is inspired by this gist:

https://gist.github.com/LiamHaworth/1ac37f7fb6018293fc43f86993db24fc#file-native-go

Most of the time, the Calculator application starts in the active user; however, sometimes the application fails to start without CreateProcessAsUserW() returning no error.

Inspection using Procmon revealed that upon launching the Calculator application, the application crashed and resorted to collecting a WerFault dump. Unfortunately, I don't see a detailed dump in the event log.

Detailed stack traces of launching 3 similar calculator applications using CreateProcessAsUserW - the first two succeed, the third fails

This error is random in nature and does not make the application reliable. I'm very clueless on what/how to debug from here and would really appreciate any help.

Correct answer

The error appears to occur due to a wrong compilation environment, where binaries created with x64 are run on arm64. Thanks for everyone’s input
