Native messaging between Brave extension and the host app is not working
I've tried to figure out why the 1Password extension in Brave is unable to communicate with the 1Password host app for a long time today. Now I give up and kindly ask for help.
When I add the extension to my Brave browser, I'm seeing the "Connecting to Desktop App" message and a spinner. The connection never successfully finishes.
I'm a software engineer myself, so here are the things I tried unsuccessfully:
Checked the extension console for errors:
💫 Looking for desktop app com.1password.1password
📤 Sending <NmRequestAccounts> message to native core <509228836>
Unchecked runtime.lastError: The message port closed before a response was received.
⏳ Timeout waiting for response to <NmRequestAccounts> from native core <509228836>
Checked the browser support logs in /logs/BrowserSupport:
Sometimes I'm getting:

The "All pipe instances are busy" error is interesting, but even closing the pipes manually via Powershell, then fully restarting all 1Password and Brave processes didn't lead to any improvement.
I also used ProcMon to check the communication between the browser and the 1Password-BrowserSupport.exe process and everything seemed relatively OK, but I wasn't able to observe any "CreatePipe` events, which I found odd.
I also made sure all values within browser_support_manifest_chrome.json are correct. I even created browser_support_manifest_brave.json with a trimmed down and confirmed correct values, even with full paths as opposed to relative paths, then changed the path in Windows registry to make 1Password use that manifest instead. To no avail.
This all started out of a sudden.
I find it interesting that the extension worked in Chrome, but when I uninstalled it and reinstalled it to test if it would still work, it stopped working (!) as well with the same symptoms.
I tested this with both 1Password stable and 1Password beta.
Any assistance will be greatly appreciated. I rely on the browser integration heavily for my work.
