Strange brake issue

I have been chasing a strange issue with my front passenger brake for quite a while now, and I wanted to see what other ideas those with more experience than me had. The car is a 2019 with 40k miles. Here's what's been happening:

TLDR; Front right brake began dragging. New slide pins, caliper, and brake line didn't fix it.

A few weeks ago, I felt the brakes strongly begin dragging while I was dragging, and when I pulled over it was obvious it was the front passenger, it was significantly hotter and was smoking a little. I limped home and let it sit overnight while I thought through my options. Curiosity got the best of me the next day and I drove it again, and there was barely any noticable drag, I could only tell at very low speeds and when I was first starting moving that there was some slight resistance. I came to the conclusion that it was my slide pins and ordered those along with new pads and rotors that I needed. While replacing all that I discovered that the front right caliper was seized, and would only compress partially, so I figured that that was my issue. I got a reman caliper from Rock Auto, which I did check and did compress properly. After installing that and checking everything I thought that I would have fixed it, but a test drive showed that I hadn't. The front right was still dragging and was getting very hot, it was like I was hitting the brakes when I just let off the gas. I found that the wheel would spin freely when I had it jacked up and the bleeder open, but once I closed it and applied the brakes it would lock up again. I went back to the forums and read about issues with the brake lines, and I replaced it, but again the brake is still dragging.

I have done some more reading and found some things saying that a switch on the brake pedal or the ABS unit could be to blame, but in all those examples there is either all the brakes are locked, there is an issue with the brake lights, or a light on the dash, and I have none of those. I have also read about bleeding the ABS with forscan and I will try that probably tomorrow if I have time.

If y'all have any ideas or suggestions please let me know

If the Forscan bleed doesn't help.....Its the ABS Module assembly* :rolleyes:
Man, I was really hoping it wouldn't be that. I guess I'll cross my fingers that the Forscan bleed works. I was doing some more reading last night and saw some things about some sort of recalibration in Forscan for the ABS, do you know if that would be worth doing?
