RTX resource pack can be selected from Global resources

RTX resource pack will load into "ACTIVE"

Maps can be selected from realm, server, or local 

Text prompts when loading into map will progress through generate world, but when "loading resource pack" appears, the software will completely crash. 

When software is reopened and reloads, Minecraft will automatically remove the global settings. 

All RTX packs were working fine prior to 1.19.20 release.
