Heroic won't load games: Cannot destructure property 'namespace' of 'asset_info' as it is undefined.

Stuck in Loading, I am using Pop OS 20 LTS and install it using the .deb file.

Yes, I had this issue as well and I fixed it already in the code so should be fixed on next version.
I'm not sure if this was introduced in the latest legendary versions or if Epic changed something on their metadata files, but they removed this namespace information we used to check if it's a game or a UE asset.
But I found a workaround and pushed to the main branch.
For now, try updating Legendary by downloading it from their github and selecting the binary on Heroic settings.
I'm not sure if this will fix it thought.
I shall release a new version this weekend with a fix anyway.

Fixed on the Beta release.
