I installed Bitcoin Core 25.0. Synchronization finished after a few days. Unfortunately, I made a big mistake, I configured the files incorrectly and now the application does not open.
I must honestly admit that this whole configuration is black magic to me.
I have a problem adding the screenshot, so I am copying the text that appears when I try to open
"Error: Invalid combination of -regtest, -signet, -testnet and -chain. Can use at most one."
How can this be fixed?
