What is about of "wireshark -v" or "Help -> About Wireshark"
Knowing which version of Wireshark and what capture software is loaded will help diagnose.

it says version 3.0.6 the only capture it loads says adapter for loopback traffic capture

The "Running on" section of the help or -v output will show information about which Npcap or WinPcap is loaded.

You're running with a slightly out of date version of npap (shouldn't be an issue).

As with quite a few similar questions on this site it is likely that the npcap service has stopped. From an elevated command prompt run sc queryex npcap to firstly check the state of npcap (please post the output as a comment) and then run sc start npcap if the service state shows as STOPPED.

output:

SERVICE_NAME: npcap
    TYPE               : 1  KERNEL_DRIVER
    STATE              : 1  STOPPED
    WIN32_EXIT_CODE    : 0  (0x0)
    SERVICE_EXIT_CODE  : 0  (0x0)
    CHECKPOINT         : 0x0
    WAIT_HINT          : 0x0
    PID                : 0

it worked thanks i love you

You're welcome, but this is yet another case of the npcap service stopping for unknown reasons. Maybe we should add something into Wireshark to detect this?

with Npcap version 0.9983

Latest version of npcap available here: https://nmap.org/npcap/
If upgrading npcap doesn't help there are steps here to work through:
