My OS is Raspberry Pi BULLSEYE. Image was burnt with the original software downloaded from Raspberry webpage.
In this case, seems some files of OS got corrupted either during download of image or during writing it on microSD card, or during subsequent use.
(1) Delete existing copy of raspios bullseye from your computer.
(2) Download a fresh copy of raspios bullseye
(3) Write freshly downloaded image to microSD card.
(4) First install dump1090-fa and then rbfeeder and see if rbfeeder works OK. If yes, then install fr24 and piaware etc.
