My phone doesn't turn on and keeps restarting when I plug it into USB

Hey there, Recently i tried to root my Samsung J6+ using magisk and TWRP recovery but it failed, when i open up the phone it just tells me that i can’t use samsung pass because my phone has been rooted but when i check using root checker there was no root, i tried flashing a new software for my phone but when i was flashing using odin my phone turned off and kept rebooting on a green screen that tells me “An error occured while installing software update”

so now my phone doesn’t turn on but when i plug it into my laptop or charger it just keeps restarting on that screen

when i try to go to download mode without pressing continue it just stays but when i press continue it keeps restarting again and again, Hopefully someone could help me fix it, Thanks.
