bootcamp "your disk cannot be paritioned"

I am currently having issues with bootcamp where i get the error message "your disk cannot be paritioned". ive tried using first aid numerous times, ive tried using first aid in safe mode, turning off time machine, and turning off filevault. Nothing has seemed to work so far. I've tried looking throughout the forums for an answer but i cant seem to find one.

I am currently on a MBP 15-inch mid 2015 running catalina 10.15.4

Loner T, if you're out there please help this poor soul.

Type 'exit' (without the quotes) at the '#' prompt, which will boot the Mac normally. Try to create a FAT32 (MSDOS-FAT) partition of the size you want Windows to be. See Partition a physical disk in Disk Utility on Mac - Apple Support for reference.

Reboot and hold Command+S, which will put you in Single-User Mode. In the black-and-white console, at the '#' prompt, run

fsck_apfs -s -o -y /dev/rdisk1

and post the output. If you get an error about it being mounted read-write, then we need to install Catalina on an external disk and boot from it to address the issue.

You may want to erase the whole internal disk (not just Macintosh HD) and restoring your backup. Also, run a SMC and NVRAM reset before your next attempt at installing Windows.

Do you have any external peripherals connected to the Mac?

From macOS Terminal, post the output of

sudo fsck_apfs -n -l /dev/rdisk1

The command can freeze the Mac temporarily.

This is a known bug in Catalina. Do you have an external disk of 64+GB, which can be wiped and Catalina installed on it?

High Sierra/Mojave/Catalina will use APFS. Unless you want to downgrade to Sierra, you will need to use APFS. Since you are restoring the 'full' system, it will be APFS.
