This involves 1. File compiled by 4.8 html executable crashing during loading process. 2. when I revert to previous version 4.7 , compiled file runs well, but when tested in windows 10 all runs well except where they need to play MP4 files within the compiled file.
According to the update status when introducing 4.8, apparently it is supposed to resolve this but it only got worse as it didn’t even pass successful compilation test.
