This is failing due to loading the dependency AssetBundles and causing a collision with the built in shaders bundles.

AssetBundles have an internal name/id that has to be unique, which is used to determine dependency lookup when loading Assets that have dependencies on other Assets.

The built-in shader internal name by default is generated based off the Project Name (Main Folder name/parent directory name of /Assets).

Your projects (or single project, if you are building multiple times with different Groups from the same Project) are generating the same ID for the bundles shader.
In the AddressableAssetSettings there is an option for "Shader Bundle Naming Prefix", you will need to set this to something unique for each Project/Build. The simplest way to do this is either by changing the Project folder name, or via setting it to "Custom" and setting a value manually.

Note: Though you are loading a textAsset which will not depend on the shaders bundle. Dependencies are connected on loading of the Bundles, not of the Asset. So something in the bundles will be using a shader.
