No one can tell you for sure. If it’s a HWID ban, you may get one of the hardware ban error codes, like ARAV0017, ARAV1017 or ARAV2017. If you don't get any of those, you can still ask support if your PC is HWID banned, although I'm not sure they'll tell you

Otherwise, the only real way to test it would be buying the game again on another account and seeing if you can play.
