For reference, sharing your local IP address is a little like saying “I’m in room 223” (local IP address) and not saying what building (network) you’re in. Someone can’t walk into 223 in a different building and get to the same room you’re in.
Honestly, even if someone knew what network you were on, a local IP address wouldn’t be that useful because even if they successfully got on your network, as long as you have a properly-configured firewall and no vulnerable network-exposed services on your system, they can’t really do anything.
Honestly, while it’s still not a bright idea to tempt fate like that, even sharing your public IP isn’t that bad for the same reasons if it’s a competent home user; the worst that can happen on a properly-configured network is that someone tries and fails to exploit vulnerabilities that aren’t there and MAYBE drum up your internet bill. Also, for most ISPs, your public IP changes pretty often anyway, usually something like every few days to a week, due to changing DHCP leases.





I agree with other people that you should futz around with your GPU drivers and different Wayland compositors first, but also, if you ever had to reinstall, there is such thing as saving your dotfiles to significantly reduce setup time.
I don’t do that because I’m lazy, but it certainly is a thing
