Issue Details

LabVIEW crashes with the following error: Fatal Internal Error 0x90FFFA4E : "AppEntryPoint.cpp".

Solution

Follow the troubleshooting steps relevant for the operating system you are using:

Windows OS

If you are running LabVIEW as a different user, this error may be caused by the Windows Feature Update via Windows 10, version 1909 Enablement Package. Uninstall this update and see if the issue still occurs.
Try force reinstalling LabVIEW.

MAC OS

Try uninstalling LabVIEW using the Terminal window.

Linux OS

In a Linux environment, this error may occur due to updates in software dependencies. NI driver software versions 18.0 and higher cannot be installed through your Linux distribution's package manager if there is a pre-18.0 NI driver on the system. Pre-18.0 NI drivers must be uninstalled first. After uninstalling you need to download and install the newer versions of the Linux drivers.

Additional Information

If the uninstalling process does not solve this problem, as a temporary workaround, try installing and running LabVIEW in a virtual machine. As another workaround, try creating a temporary new user and reinstalling LabVIEW.
