HTML5 is currently only 32 bit, could be this way for a year+. I have successfully ported 4.28(master ue4 branch) to HTML5 but UE5 is a little more challenging.
Not that I don’t believe you, but do you have an official source where it says 32 bit is been removed? I couldn’t find anything.
Yes Epic is removing 32 bit support, from the migration guide: “UE5EA does not support 32-bit platforms, and there are no plans to add 32-bit platform support in the future.”
