Kernel : 5.15.0-40-generic
Wireless Card : Realtek RTL8723BE
Suddenly my wifi is gone and there is no option to turn it on, it says "No wifi adapter found". It was just fine before, I didn't mess with any network settings and it's been 2 days now that my wifi isn't working. There has been no luck with update from apt update and apt dist-upgrade.

I don't know what else to go or to try from here, any suggestions ?
[UPDATE 02/06/2022]
Following suggestion from comments, I removed iwlwifi dan include my wireless info (gist) following My wireless/WiFi connection does not work. What information is needed to diagnose the issue?
