I have notebook Lenovo E490, which has Wi-Fi RTL8822BE 802.11a/b/g/n/ac Wi-Fi adapter, but after upgrade to 20.04 LTS, Wi-Fi not working. Has anyone experienced this problem?

When running the command nmcli device wifi list, "No device or network" appears.
When running sudo iwlist wlp5s0 scan, the result is:
wlp5s0 No scan results
