Before that I used STM32F030R8T6, there was no such problem. Tell me where I could be wrong?I am attaching screenshots of the organization of power supply and settings of the CubeMX

There is no high-pulsed-current tracks nearby. The oscilloscope measured the power lines for surges. Meals within the framework of the instructions in the manual for the low dropout regulator (TLV73333PDBVT)

Hello. I am using in my project STM32F730V8T6 with external resonator (HSE) 16.000 MHZ (XRCHJ16M000F1QB1P0). When outputting the frequency to external ports, I will experience a spontaneous frequency change (16.1000-16.1080 kHz).
