```
TypeError: Cannot create property 'pyodide_fatal_error' on number '28811048'
```
With this the same error looks like:
```
Pyodide has suffered a fatal error. Please report this to the Pyodide maintainers.
The cause of the fatal error was:
CppException: Unable to cast Python instance to C++ type (compile in debug mode for details)
```
