How does air pressure affect electronic components such as MCU, Crystal and others?

We have a product that is dust and water proof.
There is no way the air inside to go outside. And also, from outside to inside.
The product also heats yourself. The air expanded inside over temperature causes pressure to rise accordingly.
At that state if I open the cover of the product, the MCU loses the clock. and generates loss of clock condition. :smileyindifferent:
The MCU datasheet(LC60) doesn't indicate any values or test result for pressure. That means MCU works properly at all pressure condition?
If you have experienced, can you share other components behaviours at pressure such as electrolytic capacitors, smd resistors, crystals?
