As of right now the only way he’d be disqualified is if he were charged and convicted under 18 U.S.C. § 2383 - Rebellion or insurrection – which explicitly lists disqualification from holding office as part of the punishment. Even in his DC criminal case he has not been charged with this.
This ruling means Congress needs to either specifically pass a bill disqualifying him or laying out other circumstances for disqualification which would apply to him.
