Thinking back, I had run into something similar to this for some method calls on proxies - the This/Holder object wasn't the object wrapping the proxy as we expected (likely due to some lazy instantiation/wrapping stuff we do around the proxies). In that scenario, I hacked it to basically search up the prototype chain of Holder to find the proxy we're looking for: https://github.com/appcelerator/titanium_mobile/pull/8041/files#diff-16204ab8e9743a30e6e6f874a876539eR227

You are talking about the Proxy::unwrap method? Already tried that and it still crashed
