After the latest upgrade of Raspbian buster everything seems to be falling down. Softwares are crashing. And bluetooth adapter is missing. Also the bluetooth menu is missing. How can I fix this problem?

There was no backup I am afraid.– Sohan ArafatJun 18 '20 at 12:44

Make a new installation of the Raspberry Pi OS. Use a new SD Card. Check your power supply.– IngoJun 18 '20 at 17:34

Are you sure the upgrade went though successfully? Try running sudo apt-get upgrade and sudo apt-get -f install and make sure they don't report any errors.
Next, I'd check if you can get a USB BT adapter working (if you have one). That would tell you where to look next.
If none of your adapters work, you're likely having trouble with the BT software stack. Check the status and logs of bluetooth and bluealsa services.
If USB BT adapters work but the built-in doesn't, it's likely a problem in the hardware configuration. Check that BT is enabled in config.txt and there are no conflicting settings. Have a look in the kernel log (dmesg) for evidence that the BT hardware is detected and the driver is found and loaded. Then look for any error messages from hciuart service.

I tried everything. But couldn't fix anything. Again flashed with the new Raspbian. Jun 25 '20 at 1:14

If BT doesn't work after a system reinstall, I would start to suspect a hardware issue. Can you check your Pi with an older Raspbian release? Jun 25 '20 at 12:59
