if that kali kernel actually has squashfs support enabled (you can check with cat /proc/filesystems if squashfs is in the list) it might be that you are hitting the known squashfs bug with the 6.0 kernel:
this is fixed in 6.2 …
PS: if you are new to linux, kali, being actually intended as a toolbox for security maintainers and not a fully fledged distro is probably not the right thing to start with.
