Kali won't upgrade

I've installed kali linux onto a 256 gb sdcard for use on a Raspberry Pi 4. I used the pre-made image for the rapsberry pi 4 from the downloads page, and balenaEtcher to flash it to the card. After installation it boots up fine, but when I run "apt update && apt upgrade" (as sudo) it gives me the error "E: You don't have enough free space in /var/cache/apt/archives/.". This is a 256 gb sdcard so space shouldn't be an issue. When I check it using disk management on windows it shows that 233 gb is a separate partition from the kali linux partition, which is less than 10 gb. Disk management doesn't allow me to extend the kali partition to use the full space, nor does a third party partition manager, and I've tried wiping and formatting the sdcard and reinstalling, but it only gives me the same errors. Any help would be much appreciated.
