Issue
There is a known Windows bug that may cause instability when using Python in FME 2022.0 on Windows 10 (version 1909 or older) or Windows Server 2019.
Cause
As of FME 2022.0, FME now uses UTF-8 as the encoding locale, which has uncovered a Windows bug that causes a crash when using certain Python modules, due to Python changing the locale. We have patched the usage of these modules to help guard against a crash, but there may be others that we are not aware of. If you encounter this crash, please report it to Support. For more information on UTF-8 in FME 2022, please see this article.
A warning message will appear in the log if you are running FME 2022.0 on the affected version of Windows:
Python: There is a known Windows bug that may cause instability when using Python in the current locale. Please update to Windows 10 version 2004 and greater, or to Windows Server 2022
Resolution
If the warning message is logged when the translation succeeds, you can safely ignore this message. If the workspace crashes with UTF-8-related errors, please update to Windows 10 version 2004 or greater, or to Windows Server 2022.
