How to remove this Boot camp partition?

I have recently tried to install Windows on my Mac using Boot Camp. During the partitioning Boot Camp crashed. When I tried to remove the created partition via Boot Camp I got this message:

It looks like 2 new partitions have been created: OSXRESERVED (10 GB); BOOTCAMP (178,68 GB)

I have tried removing the partitions, but I get a message saying: "This volume cannot be resized."

When I enter 'diskutil list' in Terminal I get this output:

How can I go back to having only one volume? Which options are there? Will I have to reset my Mac?

I run mcOS Mojave 10.14.5 on an iMac (2017 model). (If that helps)

Any help would be greatly appreciated :)

You have a failed BC Assistant execution leaving partitions in a confused state, which it will clean up in some cases. In your specific case, given the current state, try

Step 1

diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4

diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list

Step 2

If you see only disk0s3 as the last entry under disk0, then run

diskutil eraseVolume fat32 BOOTCAMP disk0s3

and retry removing the partition using BC Assistant only.
