Could be many reasons. May seems, you may not have the rights to capture. Did you install NPCAP driver with default settings? You should! You need admin right to capture. By default, the driver is installed as admin and you can use it later as normal user. However, if you changed the options while installing NPCAP, you may switched this off.
Please try to run the Wireshark with admin rights.
