MetaMask is a couple of french fries short of a full pack, so occasionally it will act iffy. Just be sure you can rule out insufficient ETH/BNB/etc. to pay gas fees as the cause of your current situation. If you can rule that out, then it's just a matter of time before tech support can resolve your issue.
Once you're free of tech woes, good luck with your pHBD buys and journey.
