I have a hap ax lite l41g-2axd then I reset it. I netinstalled the main package of arm RouterOS v7 7.14.1 but then the master interface was unknown. Whenever I enable the wifi-qcom in the packages and reboot it, the wireless will be disabled, and vice versa. Whenever I enable the wireless, the wifi-qcom will be displayed, but the master interface is still unknown.

Forget about "wireless" package on ax devices (hAP ax lite is one of them). You need wifi-qcom package. And then configure things under /interface/wifi.

More about wifi/wireless in 7.13 and later: viewtopic.php?t=202578

can you teach me the step on how to configure or connect it to a wifi without the wireless package?

As the linked article says: on your device, you need basic routeros installed and optional package named "wifi-qcom". After you get these packages installed, I suggest you to reset router to factory default config. The rest of configuration is done in /interface/wifi (I believe that's WiFi main menu in WebFig). Documentation is here.
