Claude in Chrome extension breaks LastPass extension when both are enabled

Description
When both the Claude in Chrome extension and the LastPass extension are enabled at the same time, LastPass stops working. Disabling the Claude in Chrome extension immediately restores LastPass. Re-enabling Claude in Chrome breaks LastPass again. This is fully reproducible by toggling Claude extension on/off.

Steps to reproduce

1. Install, enable and login in the LastPass extension.
2. Install and enable the Claude in Chrome extension.
3. The LastPass toolbar icon shows as grayed out (disabled-looking), and it does not function.
4. Disable the Claude in Chrome extension.
5. LastPass works normally again (icon is active, not grayed out - needs to restart Chrome)
6. Re-enable the Claude in Chrome extension.
7. LastPass's icon goes grayed out again and stops working.

Expected behavior
Both extensions should function normally at the same time.

Actual behavior
The LastPass icon appears grayed out and LastPass is non-functional whenever the Claude in Chrome extension is enabled. Console error (from LastPass's background page, visible in chrome://extensions when Claude in Chrome is enabled):

Uncaught (in promise) Error: No identifier

    at t (background-redux-new.js:2:3398842)

This error only appears in LastPass's background console when the Claude in Chrome extension is also enabled. LastPass initializes without this error when Claude in Chrome is disabled.
