Does STM32L431 support bit band operation

[HSX.1]

What are the SRAM bit band area address and its bit band alias area address, and the peripheral bit band area address and its bit band alias area address, if supported?

There are address ranges mentioned in the Cortex M4 Programming manual -

Bit banding addresses are shown in the programming manual. Not everything is bit banded.

Therefore, STM32L431 does not support bit band operations

How did you come to that conclusion?

I guess it, I didn't get

[gregstm]

"Does STM32L431 support bit band operation?" - yes (it does)

[HSX.1]

Have you ever used the bit band operation of STM32L431?

[HSX.1]

My programming looks like this, but it doesn't work

So, are the GPIO addresses within the area which is bit-banded (see TDK's post above)?
