When I import your sample DNG, I see the same options for Profile that I see for the sample I downloaded from dpreview.com:

That threw me for a loop, but a little googling educated me: Adobe doesn't make "Adobe XXX" profiles for DJI cameras, so LR and Camera Raw use the profile that DJI embeds in the DNG (that's the "Color" profile). See the long discussion in this thread:

And in case other readers are wondering, this DNG really does contain raw data, not RGB data, as confirmed by the Metadata > DNG tagset:

Evidently you got the "Profile missing" error because you applied a preset on import that tried to apply the Adobe Standard profile (or a profile based on Adobe Standard, such as Adobe Color or Adobe Landscape).
