Identifying Sentence Error Question HELP

Opinions on Charles Ives as a composer (have always been split), with some listeners regarding him as, (at best), an entertaining eccentric, (while) others lauding him as the (most influential) composer of his age.

The error is ‘while,’ and the answer explanation says that it is a wrong conjunction. Could anyone please explain why ‘while’ is a wrong conjunction? It sounds okay to me!

“While others lauding him” doesn’t work – have you ever heard the -ing form used with “while”? It’d have to be something like “While others laud him.”

My guess for the correct preposition would be “and”… Some people regard him as weird, and others laud him as a genius.

Oh! I see my mistake. Thanks a lot, @bodangles

It doesn’t need to be so drastically revised as that:

with some listeners regarding him as X and others lauding him as Y
