Why did my WiFi, bluetooth and hotspot stop working all of a sudden?

I had this very awkward experience, today. My Samsung Galaxy A10s running Android 10 has ran into some serious trouble. I am shocked to find that my Wi-Fi is not turning on, my bluetooth is frozen and my hotspot is also not turning on. I do not realize, why this is happening. I am not a regular Wi-Fi user, I prefer Mobile networks, and it is extremely shocking to find that my device is not properly working. **My attempts to fix this** - I tried clearing the cache memory, of all apps, individually one by one, freeing up almost 120+ MB from internal memory. - I tried booting into **safe mode**, and then tried to enable Wi-Fi / hotspot/bluetooth, but *still* my efforts were all in vain. - I updated it manually to get the latest patches. But, still it is **not** fixed. - I tried *resetting* the network settings to default, but, still, my problems still persist. I do not know what else to do, to save my phone. All these features, that I lost are very very important to me. I humbly request to help me. Every help will greatly appreciated.
