Copy icon does not work

[Cucak]

   <q-icon
                    name="bi-c-circle"
                    size="24px"
                    class="text-[#B7B9CD] hover:text-[#DFE2EC] active:text-[#8C7EEF]"
                    
                    />
                  
                  
                  <q-icon
                    name="bi-copy"
                    size="24px"
                    class="text-[#B7B9CD] hover:text-[#DFE2EC] active:text-[#8C7EEF]"
                  />
                  
                  
                  
                

in quasar project all icons are working well but bi-copy does not gets displayed properly...I tried to inspect and I can see there is no :before element at all.
