HEIC Import error iPhone XR

I am currently evaluating if switches from LR to CO would leave me with less challenges (e.b. better NS support). However, during this I am of course trying to import image made with my iPhone XR intro CO, which leaving me with an error message:

e.g. "Error during import... [...] 8345.HEIC" => "file format not supported"

Oddly enough, the time stamps giving in the first column are way off, e. g. 6.7.20 08.00 while it is actually is 12.5.21 8:00...

Any help would be greatly appreciated...
