Same issue here: windows 10.

The only way I found is to pass on a remote server such as PDF.JS, for example, if you try in BLUI or Unreal it will work: https://mozilla.github.io/pdf.js/web/viewer.html?file=https://s22.q4cdn.com/899716706/files/doc_downloads/test.pdf

It seems the ifc4 schema is in the codes files but never implemented completely. It's a pity for engineering part but we can export to the more known ifc3x2 schema...

Basically, datasmith must be prepared on Revit, other than IFC can be used directly, so would be important using directly native formats.

VS22 Compile OK, but still no luck.
