Today, I have try to compile an blank html project and it works fine. My setup and OS or applications used are not involved in the crash.
Testing with importing my game into this blank project after removing all maps and meshs inside.
After compiling message : “Expression (!IsInRenderingThread()) failed in D:\Build++UE4+Release-4.17+Compile\Sync\Engine\Source\Runtime\Landscape\Private\LandscapeRenderMobile.cpp:313!” in Firefox, and then return of error : TypeError: Browser.mainLoop.scheduler is not a function.
So, still stuck…
Thank you and sorry for my bad English…
