2023 Wigo 1.0 G AT Head Unit Malfunctioning – Advice Needed

Hi everyone, I hope someone can help.

The head unit in my 2023 Toyota Wigo 1.0 G AT suddenly started malfunctioning. It hasn't been exposed to water or physically damaged. The car is now out of warranty (over 3 years old). What could be causing this issue? I don't have much knowledge about cars or anyone to consult, so any advice on troubleshooting steps or reliable repair shops would be greatly appreciated.

Thank you!
