According to the error, the lock file can't be locked. The container spins up just fine and is available if I access it via the console. Note, the above error happens after the ct is created:
module.worker_vms.proxmox_lxc.container[0]: Creation complete after 24s [id=hv01/lxc/1000] (it's called VM, but it's actually a ct)

If i try setting parallelism to 1 with terraform apply

It says the ct already exists, but only because the apply created it. It does not exist before terraform applies.

Same here. Happens with both count and for_each loops. If you specify vmid=0, excess containers are spawned. When you split the loop into multiple tf files for each vm, it works even with parallel execution.

Same error when i create 3 VMs through terraform module the first VM is correctly created with VMID 118 but the other is not created with this error:
