Wi-Fi and Bluetooth Randomly Turning Off on Samsung Galaxy S21 Ultra

I am using a Samsung Galaxy S21 Ultra powered by the Snapdragon 888 chip. Recently, my phone has been experiencing an issue where the Wi-Fi and Bluetooth suddenly turn off, and I often have to restart the device to use them again. Sometimes, the Wi-Fi cannot be turned back on for several days. Even though I have tried restarting the phone and resetting it to factory settings, the problem still persists. Can someone explain this issue to me?
