[Solved]ifconfig not showing wlan0

Hi there, quite a strange thing to me, and need your help. Belows describe the whole story.
0. Before today's story, I could connect wifi normally, and everything worked fine on my ideapad.
1. I installed protonvpn-gui via makepkg, and logged in, but I failed to connect to any node.
2. I installed tor via pacman, and snowflake-pt-client-git via makepkg, restart protonvpn with torify, but also cannot connect any node.
3. I give up and powered off my laptop.
4. The next time I open my laptop, the wifi icon becomes a wired connection icon, while the gnome setting app shows that I do connect to a wifi.
5. nmtui shows wifi connected, too.
6. ifconfig and "ip address" both shows there's no dev with name wlan0, but two dev beginning with the name "pvpn", which seems to be created by protonvpn.
7. rfkill shows wifi is both soft and hard unblocked.
8. I cannot get internet connection via my laptop, so I'm asking you sincerely for help from my Android device, if you need any other information about my laptop status, I'll type it to you ASAP.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
Maybe rather post the actual output of "ip a" and also a complete system journal:

sudo journalctl -b | curl -F 'f:1=<-' ix.io

Thanks for your reply. And it might been a long time between your advice and my reply, since it's a tough thing for me when I cannot get through the internet even if I connected wifi, that's also why I post here for help.
Because I cannot Googling or curling anything now, I copy the two outputs to pastebin.com, hope that can help:
ip a output is at https://pastebin.com/ysjrLATg
journalctl -b output is at https://pastebin.com/1eQ83800

You're making a bad assumption that there should be a wlan0. There shouldn't, your adapter is wlp1s0. You're connected with an IP, so what's the problem, specifically?

Thanks for your reply, seth and Scimmia.
My problem is that I cannot get through internet even if wlp1s0 connect to wifi.
Under the help of proton team, I use nmcli to del connections associated with protonvpn, and the internet connection becomes normal now.
Thanks again.
