Are you sure it is a 2015 Air? If it is, then I would see if you can get into recovery and try that. Also, go to the app store and search for Catalina. It should show up, and allow you to install it.

Try accessing it from the App Store link.

Once you click it, it should open the App Store page from where you can download the update tool. According to Apple's own support page, the 2015 MacBook Air should be compatible with Monterey: https://support.apple.com/en-us/HT212551

@antoniogalu @lieder1987 ah i found it. but it seems the appstore behave abnormal. 

 

• Password appstore is correct and the phone gives verification code. the appstore reject it and say ti was wrong. (phone comfirm login)
• if the Password collum left blank and press enter 3 times it force login appstore but still cant download

i sent it to technicisian tommorow. seems software issue. the battery and everything runs great.

It is possible that with that old version of Mac OS it might be extra challenging to upgrade to a newer Mac OS just because of limitations with the current one. Also there were certificate issues that require setting the date of the system into the past for some updates to work natively. Easier would be to make a Catalina USB installer on another system and do a fresh install.
