I wanted to try it once more again and STM32CubeIDE can't upload anything and shows me a message it can't connect to target MCU. What should it mean? How can it go broken??? I am very disappointed, nothing connected and MCU is out now. Are you really serious???

It doesn't help anyway, after disconnecting the board it stays frozen.
And I haven't even added a string of code after generating the project from the Cube settings.

@AK.12iselev if you are able to connect to the MCU from CubeProgrammer and erase the flash when pins 5 and 7 are connected (with power-on reset), then the issue is related to SMPS configuration.

Hello, I have finally solved it!
PWR_DIRECT_SMPS_SUPPLY with Power Regulator Voltage Scale 0 option has helped. Now it also works after disconnecting and reconnecting the board.
Thank you for your hints!
