So I closed my wallet, got an error message. Upon restart all my coins are gone, my adress has changed, seems like the wallet.dat was deleted somehow and replaced when I restarted the wallet. Believe it or not my external drive died just hours ago. So I guess I am screwed. First time in crypto since more than a year I lose coins like that....
system recovery
maybe your luck
no luck. I was able to recover the original wallet.dat from the external drive but it is damaged and the wallet wont start (error message). Sigh.
