Unprune & Re-Download Failed. Core asks for a "-reindex" due to chainstate, then fails

I was attempting to return from pruned to unpruned chainstate. Unchecked the pruned box. Core cautioned this would require re-download of the blockchain in its entirety. OK, fine. Shutdown Core to re-start and it failed, repeatedly. Since I don’t know how to -reindex, I uninstalled Core, presuming ALL data, files, directory structures, etc., associated with the program would be removed or deleted. Nope. Found the following data and structures dating to first installation:
Unprune & Re-Download Failed. Core asks for a "-reindex" due to chainstate, then fails

From the debug.log:

LoadBlockIndexDB(): Block files have previously been pruned

: You need to rebuild the database using -reindex to go back to unpruned mode. This will redownload the entire blockchain. Please restart with -reindex or -reindex-chainstate to recover.

should not be overwriting a chainstate

Error: Error opening block database

Shutdown: In progress…

If I uninstall Core again, and then Delete the folders: blocks & chainstate, will this force another download? Or do I need to Delete the entire Roaming>Bitcoin folder?

Thanks
