BUT, I'm having what I believe to be an ECU issue in my 2018 wrx...similar crap...I think a code is essentially burned in. I've done a ton of diagnosing and still want to 100% confirm before I purchase a new ECU, so I have a few more things to troubleshoot. If anyone is interested in the code/diagnosing process I went through, I'd be glad to share, but it's extensive.
I really, REALLY, don't want to go to the dealership to have them swap the ECU. I have an AP married to the car and have a ton of other mods on the car (planning for big power this year), and just foresee it being a huge hassle at the dealership. To be clear, I'm talking about the dealership just working on the car, I would NOT claim anything under warranty. I'm 99% sure this is my fault somehow.
My question is, does anyone think this process will work for swapping the ECU in my 2018 WRX?

This process was in the btz\86 service manuals, i have no idea if it eould work with a 2018 wrx as they use a hitaci ecu not a Denso. You would need to get hold of the repair and service manuals and find the swap process
I very much doubt their are eny permanent burnt in error codes or learned values in ecu, ive swapped lots in brz 86 and that sort of thing would cause issues on a swap. I think your ecu either has a hardware issue or you have a hardware or senor issue in car
