Can't really describe the issue. Its not really starting immediately (takes way longer, than it used to) and then shows this message when it does start.
Got the same problem.
Starting immediately and the MM does not start. Baldurs itself is fine.
Redownload, re-extraction and BG3 reinstall didn't work.
you are not alone in your suffering
