Question: Error, (in convert/parfrac) cannot convert to partial fraction form V2023

Is this something known or should be fixed? I check it is exists also in V 2022 for same input.

Error, (in convert/parfrac) cannot convert to partial fraction form

But for some reason I do not now understand, I am able to actually trap this error, which makes it much less serious for me, as the program can continue.

In all other cases where Maple generated such internal exceptions, it was not cought by try/catch.

So I am able to bypass this problem, but thought to check if someone can shed more light on this and why it happens.
