Troubleshooting Realtek WiFi card

I was able to go online yesterday with my laptop without any issues, but today no WiFi access. I have tried using earlier kernels, and invoked sudo modprobe rtw88_8723de, but to no avail. What would be the best way of troubleshooting this? Turning Airplane mode on and off made no difference. Thank you in advance!

please post output of rfkill list wlan and journalctl -b -t kernel -g wifi
