issues connecting to local network since update (Sequoia 15.3.1)

Hello,

Since updating to Sequoia 15.3.1 last week I have been unable to connect to my local network (on local Wi-Fi).

I am unable to connect to my local server and I cannot find or connect to any printers on the network - in the default tab, none show up, and when I enter the IP address instead I get the error message "Unable to communicate with Printer at this time". None of my colleagues' MacBooks have this issue and I can't see any obvious settings that are different.

Speaking of local servers - even before updating, I could connect to my local server, but all the files were "read-only" and whenever I tried to save anything, my Macbook would freeze and need force restarting.

Any ideas how I could try to fix this and get access to my files and printers? I unchecked "Limit IP address tracking" and have Firewall disabled.

Totally lost and in need of a tech hero!

Thanks,

Soph
