Why MATLAB on Macbook Pro behaves weird while working with BLE devices?

So I am trying to work with BLE devices on MATLAB. It sometimes says "Bluetooth Low Energy is not supported on this computer or Bluetooth is not turned
on." (which is clearly not true) and it sometimes works. Plus, if I try to reset the BT module on Macbook, MATLAB crashes. This doesn't happen on the Windows machine.
What's wrong?

I see reports the BLE has problems on Catalina, such as at https://www.ikream.com/2019/11/how-to-fix-problems-with-bluetooth-on-macos-catalina-36499 . I would be wary about the advice to reset the PRAM though. See the alternative advice at https://www.techradar.com/how-to/macos-catalina-problems-how-to-fix-the-most-common-issues
Tried the alternative advice. Doesn't help. I have to run the command "blelist" like 10-12 times before the error message goes away and I am shown a table of available ble devices.
I don't know. Mathworks Support might have heard more.

I have heard that these issues are known, and the concerned parties may be investigating further.
