Cannot remove bootcamp partition

Hello, a while ago I created a bootcamp partition. Now there is now possible way to remove it. I also cannot even install bootcamp. Another problem is that, in disk utility, even when booting into recovery or internet recovery mode, it always crashes when I click partition. Here are screenshots of diskutil list and disk utility. I want to merge the disk BCMP into macintosh hd and then create a fresh bootcamp partition. I cannot do this because disk utility crashes whenever I press partition. WHen I open bootcamp, it says "the startup disk cannot be restored to a single partition". So when I format that disk as something else, I only get the option to "install windows 10 or later version" rather than "install or remove". After I do that it says that the partition could not be created and just steals the disk space and I have no way to get it back as disk utility crashes when I try to partition.

Let us do the Internet Recovery method. If we run into any issues, we can switch. In IR, click on Utilities -> Terminal.

Destroy the current GPT
- diskutil unmountDisk disk0
- sudo gpt destroy /dev/disk0
Create an empty GPT
- sudo gpt create -f /dev/disk0
Add GPT entries in sequence, and unmount as necessary.
- EFI
  - diskutil unmountDisk disk0
  - sudo gpt add -i 1 -b 40 -s 409600 -t efi /dev/disk0
- macOS
  - diskutil unmountDisk disk0
  - sudo gpt add -i 2 -b 409640 -s 1167968768 -t apfs /dev/disk0
- Bootcamp
  - diskutil unmountDisk disk0
  - sudo gpt add -i 3 -b 1168379904 -s 298434560 -t windows /dev/disk0
Post the output of
- sudo gpt -vv -r show /dev/disk0
- diskutil list
