Does not start anymore with latest FreeCAD 0.22dev and Ondsel ES 2024.2 builds

[NothanUmber]

Getting the error message "DLL load failed while importing QtWebEngineWidgets: The module was not found" when trying to start the Render workbench. Getting the same error message in Ondsel 2024.2 and FreeCAD 0.22 (current build 37213).

Hello,
Thank you for reporting!
Yes, FreeCAD core team removed QtWebEngine from dependencies shipped with 0.22 (with no consideration for workbenches using it). https://forum.freecad.org/viewtopic.php?p=757394#p757394

I'm gonna find a solution and I'll come back to you.

Hello @NothanUmber,
It took me a while, but I think I've found a solution: #408. Could you tell me if it works for you please? Thanks!

Hi @howetuft,
thank you for investigating! At least the previous error doesn't pop up anymore!
Now I get the following error when trying to load the Render workbench:
FreeCAD 0.22.0dev 37645, Render v2024.6.5

The Arch (BIM) workbench itself seems to load (using the version integrated with FreeCAD).

Edit: Seems to work in Ondsel 2024.2 though - great!

Edit2: When starting it in Ondsel (or trying to start it in FreeCAD 0.22) it seems to open dozens of Windows without content (On first sight this seems not to happen when not trying to start the Render workbench):

Thank you for your feedback. This is yet another problem: the Material handling system has been (is being) completely overhauled in 0.22. It's presented as an improvement but, in reality, it breaks all the codes that used the historical version (including Render...). OK, I'm going to see what I can do to circumvent this issue...
