Hey y'all, I've been trying to install this ROM but no matter what I do I can't get it to install correctly. I navigate to where I have the flash-all.bat saved and I run that using ./flash-all.bat in powershell and it gives me this output...

PS C:\platform-tools\proton-aosp_redfin_11.2.0-gapps\redfin-rd1a.201105.003.c1> .\flash-all.bat

I originally tried on a rooted version of the November update, then I tried installing from a stock November update, then a stock October update, eventually gave up and install and rooted October's update. I'm now trying again and having no luck. Whenever I search the error 'FAILED (remote: Failed to write to partition Not Found)' everyone just says "Make sure your adb and fastboot is up to date" but it IS up to date, I downloaded a fresh copy of the tools straight from google the night I tried. I have the latest adb and fastboot, I have the latest and correct USB drivers. Gonna go try on my roommate's PC but if that doesn't work I really have no clue what to do. Initially when I tried to install this I semi-bricked my device for a few hours and had to make an XDA post about it. I'd really like to try this custom ROM, if anyone has any suggestions I'd appreciate it.
