Okay so I have uninstalled and re-downloaded both the base game and phantom liberty 3x now.

How do I get Cyberpunk to recognize that Phantom Liberty is installed.

Note it doesn't matter if I use Galaxy or the offline installers.

The expansion worked before 2.1 (2.11 now) but the game acts like it was never there.

Is there a specific launch parameter or a toggle that needs to be hit now?

Help please and thanks!

First off, do you have all the files?

Check against this list I posted here (this is for 2.1, but the number of files is the same):

Second, run the game locally and directly from the main Cyberpunk2077.exe located in the install directory.
Cyberpunk 2077\bin\x64

Yes. I have all files. I also run it directly to avoid the double launcher. I install with verification (though not available for Phantom Liberty). I also tried gog galaxy, but it hangs at 92% which is typical.
