Steps to reproduce:
Go online and download any .mcpack or .mcworld file.
select the option to open it in minecraft.
Watch as the import fails
Observed results
The import fails and the file is not useable
Expected results
The file successfully imports and is now usable as either a world, texture pack or addon pack.
Also occurs on the most recent version of bedrock edition.
I’ve experienced this on build 3678051. This issue also causes failures to import behaviour packs and resource packs.
I tried it on iOS and the issue also appears to be present there.
