RH 2022 - Import of MarkDown reports "Application Error" and other oddities

As the subject line indicates, I am using RH 2022 and experimenting with importation of MarkDown files (.md) and am getting unexpected behavior.

Selecting File\Import\Markdown File, then choosing the desired file, I briefly get a "Markdown Import" progress dialog in the lower right corner, which is quickly covered by an "Application Error" dialog, which, when Dismissed, returns to the "Markdown Import" dialog ... which never ends until Dismissed.  However, the file is apparently correctly imported as a topic of the same name (as the md file.)  I am new to Markdown syntax and so my testing is quite simple.

Given the apparent success of the initial test results, I wonder if these are simply nuisance bugs, or is there something to worry about!
