Trying to connect to testnet

I downloaded the binary and configured it per instructions at lovelace academy.  I left it running as it was syncing successfully until it got to around 84%, then it stopped making progress and instead keeps spitting out errors and warnings based around "invalid block"
Some errors:

It keep repeating these and other warnings over and over again.  I don't know how to fix the "Invalidblock" situation.  I tried rebooting but that didn't help.  Is there a way I can delete the invalid block or ledger entry, or delete all the synced data and try again?
Thanks

user1071: I don't think it should be possible to fully sync testnet with recent versions of cardano node. There was a divergence in ledger rules last year. For this reason, it is deprecated and no one should be using it.
Look at using either preview or preprod testnets. Config files can be found here: https://book.world.dev.cardano.org/environments.html
