@Karthikchary23 either you manually edited Kubo config file, or it got corrupted in your filesystem.

This made the Identity.PeerID no longer match the Identity.PrivKey in .ipfs/config.

A quick fix is to replace these two values with a new (consitent) identity.

You can generate it by moving .ipfs to different directory and starting Desktop app again. It will create fresh config in .ipfs/config. Copy Identity.PeerID Identity.PrivKey from this new profile, then shut down Desktop app, restore the old .ipfs directory, and start it again. It will have your data but will use fixed PeerID.

ps. If you need more support, open a thread in https://discuss.ipfs.tech/c/help/13
