Building DLC with Http chunks in project launcher fails at the “UAT post launch cleanup” stage. It also happens with a newly created project. This bug seems to have appeared in version 5.3

BUILD FAILED
Despite the error, all files appear in the build directory. Except for manifest file, which for some reason is created in CloudDir, instead of ManifestDir, like it did in 5.2
.uplugin for our DLC plugins typically looks like this:
{
"FileVersion": 3,
"Version": 1,
"VersionName": "1.0",
"FriendlyName": "DLC",
"Description": "",
"Category": "UGC",
"CreatedBy": "",
"CreatedByURL": "",
"DocsURL": "",
"MarketplaceURL": "",
"SupportURL": "",
"CanContainContent": true,
"IsBetaVersion": false,
"IsExperimentalVersion": false,
"Installed": false
}
DLC plugin goes into Mods folder, not into Plugins. To build it, add and set up Android DLC profile in project launcher.
