I wasn't able to directly reproduce your problem but I pushed a change which should prevent from such error.
BTW, can you share info about your display?

Yes, the latest birdy runs, but after that, my whole screen is completely black.

Hotkeys like b or f work since there is a mark cross symbol, after I Esc, nothing, no screenshot image is saved into my directory or saved to a clipboard.

Esc just exists without save. If you want to save to a clipboard press Enter.

Can you try to run several times(like 10) and check whether you always see a black screen or sometimes the actual screen captured?

f doesn't work at all, after Enter, b's result is put into my clipboard, check the attachment.

No matter how many times I tried birdy, my screen is always black, I cannot see anything.
