Unable to stub closure in static function

Overview

When I try to stub closure with will in a static function, it shows error "Unable to infer type of a closure parameter", if I specify the type in the closure parameter, it can be built successfully, but crash when running test.

Example

Source class

class NetworkHelper {
    // MARK: - Network requests
    static func get(
        url: URL,
        token: String?,
        completion: @escaping (Data?, URLResponse?, Error?) -> Void
    ) {
        var request = URLRequest(url: url)
        request.httpMethod = "GET"
        // Sample server doesn't need a token as it runs locally
        if let token {
            request.addValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
        }

        URLSession.shared.dataTask(with: request, completionHandler: completion).resume()
    }
}

Test class

func testRequestOtpSuccess() throws {
        let helper = type(of: mock(NetworkHelper.self))
        given(helper.get(url: any(), token: any(), completion: any())).will { completion in //This will show error when building
            completion(nil, nil, nil)
        }
        // The following ways will crash the app
        // error: memory read failed for 0x0
        given(helper.get(url: any(), token: any(), completion: any())).will { (completion: (Data?, URLResponse?, Error?) -> Void) in
            completion(nil, nil, nil)
        }
        given(helper.get(url: any(), token: any(), completion: any())).will {
        }
    }

Expected Behavior

It should be able to stub and run without crashing

Environment

• Mockingbird CLI version (0.20.0)
• Xcode and Swift version (swift-driver version: 1.62.15 Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51) Target: arm64-apple-macosx13.0)
• Package manager (SPM project)
• Unit testing framework (XCTest)
• Custom configuration
  • Mockingbird ignore files
  • Supporting source files

It works if I do this:
Change static to class

given(helper.get(url: any(), token: any(), completion: any())).will { url, token, completion in
// verify
}
