ssh agent no longer working

I have been using the 1 password ssh agent without problem for the last 4 months or so, specifically for git commit signing/ssh repo access under WSL (and using VSCode). However I started running into issues about a week ago when trying to make a git commit in vscode getting an error along the lines of error: Load key "/tmp/.git_signing_key_tmplXrHNk": invalid format?. At the time I had been messing around with changing the hostname and mac address in WSL and assumed it was related to that. After setting everything back to normal and restarting socat/npiperelay I was able to get the ssh agent working fine yesterday, but it is now broken again today and I have been unable to fix it this time.

I used the instructions on this (third party) https://dev.to/d4vsanchez/use-1password-ssh-agent-in-wsl-2j6m for setting it up in WSL and the https://developer.1password.com/docs/ssh/get-started to setup the Windows side.

Running ssh-add -l under WSL I am currently receiving the error error fetching identities: communication with agent failed, and under Windows (via command prompt, power shell, and gitbash/mingw) I get Error connecting to agent: No such file or directory. Running $ ssh -T git@github.com in Windows gives Load key "C:\\<redacted>/.ssh/id_ed25519.pub": invalid format
git@github.com: Permission denied (publickey). At no point of any of that am I getting an authorisation request in 1password even though I was previously.

In the current log for 1password, I'm seeing a couple errors show up during launch of the app, but I don't know if they were there previously or are related:

Turning the ssh agent off and on in the developer settings doesn't seem to reveal anything in particular:

No further error messages or anything obvious.

The 1password app itself (and the firefox browser extension) seems to be working fine and I was able to create an account for these forums and login without any issue. I've restarted wsl, 1password, and the computer a few times but nothing seems to make it work. As far as I can tell the ssh agent just isn't receiving any requests and causing everything to time out, but I have no idea why. Any help would be greatly appreciated.
