    Hello,

    I’m using Windows 10 v. 1903, fully updated.

    Lately, I’ve been having issues with Qt Creator crashing. However, the entire app doesn’t seem to be crashing as the Live Server doesn’t actually close. If I reopen Qt Creator, it will open a new Liver Server window on top of the previous one. There doesn’t seem to be anything I can do in particular to cause this to happen but it tends to happen within the first 30 seconds or so of opening Qt Creator but sometimes everything works fine for much longer, even a couple days. The crash occurs whether or not Live Server is running. Sometimes it will crash by making simple changes to Qt Creators options. Also, I can start Qt Creator then leave the it and work in another program (such as Firefox or something), Qt Creator will not crash during this time, however, once I click back into Qt Creator, it will often immediately crash. Here is what I’ve tried so far:

    • Run as Administrator.
    • Clean and re-build all projects.
    • Close all projects, then manually close Qt Creator so no projects are open when Qt Creator starts (Qt Creator has so far not crashed if no projects are open).
    • Keep the workspace empty of any projects then start a new, empty project. It will then eventually crash.
    • Completely uninstall Felgo, delete all related folders inside AppData and ProgramData folders, clear all entries I can find in Windows Registry, and delete any ‘build’ directories I can find. Then restart the computer and reinstall Felgo. Crashes occur as before even with only creating a new, empty app.

    Since the problems are app-independent, it doesn’t seem the normal debugging methods are applicable.

    Any thoughts on what I can try or where I should look for more information on the problem?

    Thank you,
    Eric

    After digging through some Windows event logs, I found that the current version of Qt Creator can have some issues working with GeForce 1080 drivers v. 441.08. Once I replaced my NVIDIA drivers with the previous version 431.86, the crashes stopped.
