Well the Senate killed the earlier bill. There's a decent chance they pass the Ukraine/Israel aid bill without this amendment. It would then be stricken in reconciliation. Unfortunately there's also a decent chance the Senate passes it because this version probably fixes things the Senators had problems with.
If it does get passed there's a very good chance there's a court order to prevent anything until the courts rule on the constitutionality of the law. If Bytedance loses that there's zero chance they sell though. The US market is not big enough for them to jettison an international company.
