Can't remove bootcamp partition

When I used bootcamp assistant on my macbook pro 2016, it created a bootcamp partition, however shortly in the proces I got an error asking . When I launch bootcamp assistant again, I cannot get past the warning ("the launch disk cannot be divided into partitions or be recovered as one partition". However, there is a bootcamp partition active . So I'm wondering how I can either use that partition to install windows or, how can I restore into 1 partition without erasing my MacOS part of the disk?

Help is greatly appreciated, thanks!
