Internal Warning 0xF7CF2FC3 OMUDClassLinker.cpp line 4955 when launching built executable

After launching the built executable from one of my projects I get the following internal warning:

Error dialog box

Internal Warning 0xF7CF2FC3 :  'OMUDClassLinker.cpp', line 4955

LabVIEW version 20.0b.52

For assistance in resolving this problem, please contact National Instruments Support.

Log from %LOCALAPPDATA%\Temp is attached

Which points to: DWarn 0xF7CF2FC3: Must run UpdateAllDataDefinitionDependencies before calling this function.

The application still seems to launch and function correctly (not fully tested yet though).

I tried creating a completely new project file and build spec, and only adding the one file to the build, but get the same error.

Any ideas on what could be causing this?
