unresponsive SSH raspberry zero w v1.1

Hello, i have a rpi zero w v1.1 , i had it in my basement for almost 3 years and i decided to make it an MQTT broker. so i wiped the previous OS and flushed a new. after my fist log in via ssh ... i noticed that the service is freezing. sometimes it stuck after entering password, sometimes when i type it freeze. i tried to flush : 1) Raspberry Pi OS bookworm (also tried the lite version with no GUI) 2) Raspberry Pi OS bullseye (the same as well, no GUI). can anybody help me please?

I suspect the SD card to be faulty from your description. Do you have another computer where you can check if the SD card is error free?

i checked with 2 sd cards. i don't think that this is the problem

That is not an answer to my question!

both sd cards are not faulty

So you have tested them?
