Thank you very much for your reply. According to the method you provided, I saw that the log shows that there are illegal characters in the path of STM32MatTarget. This can also explain why I had no problem creating the project for the first time, bu...

I encountered this issue while using Simulink and Cubemx for joint development, and then when I opened Cubemx separately, I found that the generated code would freeze.

It can run during the first code generation, but it will freeze during the second code generation
