MCSDK generation error : Error = zip END header not found

[wcx8229]

Hello,

There is a error during code generation phase on MCSDK.

2025-05-23 19:02:39,600 ERROR [LineInfo_to_exitCode.log_LineInfo] Error = zip END header not found
2025-05-23 19:02:39,601 WARN [LineInfo_to_exitCode.log_LineInfo] Failed to launch self-upgrade

But, click RUN CUBEMX button, the tool can be opened and generate code that can be compiled successed on IAR.

Will that error have a negative impact on the program？

the attachment files include : 3 pictures of configure and generation.
