Unable to export to HTML


I built a small game in 4.24.3 and I wanted to export it to HTML5. UE 4.24 does not support that so I installed 4.23.1 instead and converted the game to the appropriate version. However, I still can’t get it to export. The process starts and goes on for hours without doing anything. For reference, exporting the game to .exe only takes a few minutes. What is going on and what can I do about it?
