Try removing R73. Why is it there?
What is the load capacitance of X1? Would have been useful to include part number.

Hi,
I just removed the resistor and nothing happened. I also changed the MCU just in case.
Part number is here: ABM8AIG-25.000MHZ-12-2Z-T3
Also I attached the full schematic.

Hi,
I re-soldered all the MCU components but I couldn't measure the voltage on DSI12 pins. When I connect them together I can't run the code. I have to split the DSI12 pins. Can you please share the DSI12 pins effect on oscillator ?
Thanks

Connecting VDD12DSI and VCAPDSI to 3.3V doesn't look right.
Any STM32 pin with a "12" in its name typically wants to live around 1.2V. Similar for "33" and 3.3V.
