File "c:\Users\Administrator\.vscode\extensions\haas.haas-studio-2.3.1\asserts\burntool\haaseduk1\flash_program.py", line 1
SyntaxError: Non-UTF-8 code starting with '\x9a' in file c:\Users\Administrator\.vscode\extensions\haas.haas-studio-2.3.1\asserts\burntool\haaseduk1\flash_program.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
```

Start with asserts/burntool/haaseduk1/flash_program.py and reproduce the reported flash command from the log. Inspect the first line and its encoding handling; done means the script starts without the reported SyntaxError and the relevant flashing test or command proceeds.
