Error: A serious internal error has occurred, see debug.log for details

Hey,

If I knew german it might help.

Not expert on litecoin core errors, but looking at the log i’d go check this file.

Corrupt block found indicating potential hardware failure; shutting down

I’d delete the blockchain copy you have an redownload it from scratch. Might take a while depending on your internet connection
