[Question] flet build windows compilation hanging

[alieandm]

Question

I'm trying to build an app using 'flet build windows -vv' and it is hanging repeatedly part way through compiling packages into the serious_python temp folder.

VERBOSE: Compiling 'C:\Users\me\AppData\Local\Temp\serious_python_temp45cc1955\pypackages\mysqlx\protobuf\mysqlx_notice_pb2.py'...
VERBOSE: Compiling 'C:\Users\me\AppData\Local\Temp\serious_python_temp45cc1955\pypackages\mysqlx\protobuf\mysqlx_pb2.py'...

VERBOSE: Compiling 'C:\Users\me\AppData\Local\Temp\serious_python_temp45cc1955\pypackages\mysqlx\statement.py'...

This is the last line.

If I keyboard interrupt out at any time (I've let it sit a long time and it doesn't move)- I get this in the traceback:

I'm running flet 0.20.2

Anyone have any idea what might be causing this?
