STM32N657X0-Q ST-Link error (DEV_CONNECT_ERR)

Hey ho everyone I'm a Noob with all this, just surface level knowledge.

I'm on Linux ((Ny)arch btw.) newest version. First everything worked switched boot mode (cant remember if boot 1 or 0 as no combination works now) and i could connect. Then i wanted to test 5V pins and out of laziness i shorted +5V with and LED. Had an error on the power status, repluged and everything worked again (proceeded testing pins without shorting). suddenly a few days ago i had the dev connect error solved it via boot 0 and 1 both to the right on the next day suddenly not even that worked. did a bit of switcheroo that worked until it suddenly didn't even with any position. tried reinstalling (MX, Prog and IDE) tried adding myself to the uucp group didn't work tried the whole procedure as root but Nyarch wouldn't let me open my files and i simply was to lazy to do it via CMD. now i have sometimes the problem with DEV_CONNECT_ERR in any boot position and sometimes it just tells me UR connection mode is defined with SWrst reset mode (in any boot position). Tried erasing flash and stuff but can't because no connection.

probably forgor to mention some stuff so if there is any questions pls ask so because i would be really grateful if someone could help me solve this issue.
