Great, GDAL-GRASS problem solved.

--> run this on command line, to get the import done

You are hit by a current GUI bug:
https://github.com/OSGeo/grass/issues/648

which is unrelated to GDAL.

FYI I did not encounter any issue during the compilation and
installation processes.

Yes:

Best is: run the import on command line for now.

For the unrelated GUI bug:
- either switch to GRASS GIS 7.8, or
- wait for the bugfix in G 7.9 (which is a dev version anyway). For
this you can subscribe to the bug to see the related updates.

HTH,
