HTML 5 Uobjectglobals.cpp launch error UE4.21.1

Goodmorning,

I have a default C++ project without any plugins or additional content. When launching for HTML5, the build seems to be successful, but during deployment (and compiling the webassembly) I get the following error:

As everything is default, I have no clue what could be wrong.
Any help is appreciated.

Check your experimental/beta plugins. The main one that I had causing an error was the “MDL/AxF Importer” plugin. But there could be others. Please see this thread: Expression (InOuter || (InClass == UPackage::StaticClass() && InName != NAME_None)) failed - Platform & Builds - Epic Developer Community Forums for more possible plugins to disable.
