This seems to be caused by the same root issue as https://github.com/tldraw/tldraw/pull/660#issuecomment-1113170053. In this thread, @andarist was mentioned as potentially being able to help.

@tomayac I'm on vacation rn but I might take a look in a week when I get back. Don't hesitate to ping me again if I don't - sometimes things just slip through the cracks

Enjoy your vacation! If we find a fix for this, eventually tldraw could use the module as a direct dependency, rather than maintaining a local copy.

@aradhyakalva the most likely fix for your problem is to add this to your tsconfig.json::

{
  "compilerOptions": { "lib": ["DOM"] }
}

This seems to be fixable as per the instructions given in the comment above.
