problem with the virtual network in virtual machine manager

so i installed KVM and saw that the virtual network is inactive. i tried to activate the default network but i get this error: Error starting network 'default': Unable to create bridge virbr0: Package not installed

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 108, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/network.py", line 69, in start
    self._backend.create()
  File "/usr/lib/python3.10/site-packages/libvirt.py", line 3508, in create
    raise libvirtError('virNetworkCreate() failed')
libvirt.libvirtError: Unable to create bridge virbr0: Package not installed

it says that a package is not installed but i don't know which package is the virtmanager referring to?
also tried to create a NAT network i get the same error.
searched the whole internet but i couldn't find any solution

Try rebooting you computer and/or install standard kernel+headers.

dakota, I didn't use the terminal to make my virtual machine. i used the virtual machine manager app to create a virtual machine
