Issue with the extension running in devcontainer

Trying to open an excallidraw file in devcontainer inside a github codespace.

Steps to reproduce:

• create a github codespace
• add devcontainer config file with extension such as: "customizations": { "vscode": { "extensions": [ "pomdtr.excalidraw-editor"] } }
• trying to open a excalidraw file: nothing happens
• checking extensionhost output, getting following error:

Having similar issue. In my case I'm using devcontainer locally (no codespaces) and the extension has worked fine in the past, however if/when I open the project "in a unique volume" the plugin appears greyed out in the extension pane and excalidraw files are not recognized when opened
