I can not drag photos from PM to Lightroom anymore. I am using PM 6.0 Built 5820 and Windows 11.
Just want to clarify here: Are you actually using windows 11 or is this a typo? If you are on a pre-release version of Windows, that could explain why things aren't working correctly.
That being said, what file types are included when you do the drag and drop? I have found that LR will react differently depending on what types of files you are dropping into it, but that there is generally way to make it work. Let me know what file types you are working with, what version of LR you are on, and what camera is producing the images?
