No such file or directory error when attempting to attach to gdb with pwntools

I am attempting a binary exploitation challenge, but am yet to even get round to trying to exploit it as I'm having some trouble with pwntools.

My code is currently very simple:

from pwn import *
p = process("./restaurant")
gdb.attach(p)

but when it launches with gdb (with pwndbg extension) I am met with the following

Reading symbols from ./restaurant...
(No debugging symbols found in ./restaurant)
Attaching to program: /home/dnw/Desktop/htb/pwn/pwn_restaurant/restaurant, process 2704

26  ../sysdeps/unix/sysv/linux/read.c: No such file or directory.

I get the same error if I run it without attaching it through pwntools and instead attach it with gdb -p PID but not if I just open the program in gdb (gdb restaurant)

I have been banging my head against for wall for hours trying to solve this so any insight/help would be great.
