Thermal runaway, what’s fixed it?

I’ve got a CR-10S that’s been having thermal runaway problems. I’ve replaced the thermistors, upgraded the board to BTT SKR V1.4, marlin firmware, TCM2209 drivers, ohm checked the wiring, deep cleaned the hot end, cleaned out the thermistor pot again in the hot end, checked the heating element. Did a 25-30 minute dry run at 240c earlier today, no issues

Printing with PTEG at 240c nozzle temp, thermal runaway after 6ish minutes. I don’t know what else I’m missing to fix this problem

BTT SKR V1.4 upgrade, need help

So I’m little over my head with this but so far I know the board isn’t bricked. Upgraded because 1. It came with the printer when I bought it 2. I keep having “THERMAL RUNAWAY” errors with the Creality controller. I’ve replaced the thermistors twice so I’m thinking the board is the issue.

I followed the instructions from BTT, created and loaded my firmware but I don’t have a working screen. In the Marlin firmware I have the CR10 stock display enabled and only EXP1 plugged in (doesn’t matter if both are plugged in, still inop). On top of that, Windows 11 is being an asshole and won’t install the INF driver for the BTT board to communicate. Has anyone else done this upgrade and been successful? What am I missing?
