Touch died one day after battery replacement

I replaced the battery myself, folowing the guide on the oneplus 5 here. Everything went well and worked when i was done. I am 100% shure the touch worked after i was done. I left the phone charging over night to start the battery calibration. When i checked the phone the next day the touch wasn't working at all, no reaction, nothing, not in the OS or in the recovery screen. It seems like damage from the battery replacement but i find it strange that it only stoped working a day after. I reopend the phone to checked and reseat the connectors that need to be unpluged for the battery replacement, no change. I updated the OS and reset to factory settings wich also didn't help (i use LineageOS). Any ideas on how to fix this or what the problem even is?

additional info:

-I used 70% isopropyl alcohol on the battery to remove it, i was carefull to remove all fluid i could see afterwards -could it be water damage?

-the screws for the speaker got mixed up on reassembly -are they not all the same lenght?
