Why Is the Touchscreen in My Kia Grand Carnival Lagging o r Freezing?

The infotainment touchscreen in my 2019 Kia Grand Carnival often becomes unresponsive o r freezes while switching between apps o r navigation. Sometimes I have to restart the car to make it work again. Has anyone else faced this issue in Pakistan? Could it be related to heat, outdated software, o r hardware defects?
