So I did the reindex-chainstate=1 and removed the pound sign. Now Bitcoin Core wallet is running again, but now it's starting back from 2009, which was the reason I was afraid I'd have to do.
If yes (you don't know if it's pruned )
For bitcoin-qtwith GUI go to your
settings>options
You should see your prune settings like this
if it's checked ✔️ then you are pruned and running re-index will probably start the whole sync process from the beginning just as @nc50lc posted in this comment
