In October 2025 I had this exact same problem with Tpm 2.0 and HVCI in my main account on my computer tried fixing it talked to the support team and I got it fixed (without knowing) because only after like 15 replies they were finally able to tell me I was restricted from playing for 30 days, fine I waited and in November I was finally able to play, but about 3 days ago I logged in to play in my main account in my computer played like 2 games and in the end of the second one I got the exact same error went to check everything was on and working properly I could even play in another account without Vanguard problems or restrictions in the same computer the issue appeared, I could also log in and play in the range in my main account in a laptop I have here without any issue (but I cant use the laptop to play comp it has a lot of fps breaks even in the range and the gameplay isn't smooth, but I can stay as long as I want there without those problems) talked to the riot support again after 3 days of email back and forth they finally tell me I have been restricted from playing in my main account for 30 days (they say it was bind to my account, so I don't know how I can play in the laptop without the issue ) the thing that frustrates me is that I had everything on and working properly how did the restriction even spawn? 30 min after that I was already in a friends account playing without issues and I didn't change any thing in the settings and in my BIOS. Why does this keep happening, and is there any way to prevent this from happening again?
