ENETDOWN on macOS 27

[OctoNezd]

Hi. I am running macOS Golden Gate beta 27.0 26A5416b. It seems that something broke with my web-ext.

When running this:

web-ext run -f firefoxdeveloperedition -p oldlander-test --keep-profile-changes --start-url https://old.reddit.com/r/cromch --source-dir ./dist

I see firefox window popup, instantly close, then I get hit with this:

[/Users/octo/oldlander/node_modules/web-ext/lib/firefox/remote.js][error] Error: read ENETDOWN
    at TCP.onStreamRead (node:internal/stream_base_commons:216:20)
    at TCP.callbackTrampoline (node:internal/async_hooks:132:14)
[/Users/octo/oldlander/node_modules/web-ext/lib/program.js][error]
Error: read ENETDOWN
    at TCP.onStreamRead (node:internal/stream_base_commons:216:20)
    at TCP.callbackTrampoline (node:internal/async_hooks:132:14)

[/Users/octo/oldlander/node_modules/web-ext/lib/program.js][error] Error code: ENETDOWN

If running with verbose, I see a bunch of simillar errors:

[/Users/octo/oldlander/node_modules/web-ext/lib/firefox/index.js][debug] Firefox stderr: sandbox_extension_issue_file_to_process failed for /Applications/Firefox Developer Edition.app/Contents/MacOS/plugin-container.app: 1 (Operation not permitted)

My terminal already can do app management and has full disk access:

I tried moving the app next to my addon, and do it like this:

web-ext run -f ./Firefox\\ Developer\\ Edition.app/Contents/MacOS/firefox -p oldlander-test --keep-profile-changes --start-url https://old.reddit.com/r/cromch --source-dir ./dist

But it still crashes and throws same errors.

If I run the command while firefox is running, I get the ENETDOWN still, no operation not permitted errors, but firefox is left open and address bar in that tab is striped red with robot icon. I can connect from other firefox to that one just fine:

I dont see anything interesting in devtools. I tried recreating profile with no success.

Version:

yarn web-ext --version
10.6.0
