Start with WasmBrowserTestRunner.cs at line 75 and WasmTestBrowserCommand.cs at lines 86 and 152, then inspect the WasmTestOnChrome-CLR-ST-Batch-2.WorkItemExecution failure. Reproduce or analyze the WebDriver DevTools session error around Target.setAutoAttach; done means the browser test leg completes without this exception.
