There are no errors in the code you posted.

If you encounter errors in CubeMX generated code, please include the IOC file used to generate that code.

thanks for the answers. further analysis of the problem I voiced showed that in an empty project with the same configuration, enabling interrupts does not cause an error. Only when I add the library for working with lsm303dlch. I will look into it further.
