ERROR CODE 1:86001S:89001S:9C:-13561655840

I am getting this error code as well, actually my son is. error code 1:86001s:89001s:9c:-13561655840 First we are on xbox.  I own BF6 and my profile is launching fine. My son has been playing under his profile since launch.  It' had been flawless. Once the REDSEC update dropped I can play on my profile. But his account is getting the error.  I checked his clearances on my family account and he's greenlit(by me) to play anything. I have reset my modem, the xbox(a restart and a hard shutdown), also a wholesale reinstall of BF6.  Nothing worked.  Any tips would be appreciated.  Also If I find anything I'll let you all know. I'm in the same boat as Ironheart UK.
