I am using 100 pin, STM32L4 mcu. After i updated to cubemx 4.19.0 a few days before, it takes more time to generate code for larger projects (more peripherals), which goes upto approx. 3 to 4 minutes. For smaller projects, the code generation time is normal. One more problem, is that clock configuration tab becomes less responsive over time. This was not the case before even when i am using previous versions of cubemx.
