@abampalwar As a blind guess, perhaps a Spyder instance was inadvertently left running? Try launching it from the Anaconda Prompt with
spyder --new-instance, as well as the steps listed in the Spyder Troubleshooting Guide, specifically the Basic First Aid and Emergency CPR sections, which resolve the great majority of Spyder launch issues.
If it still doesn't launch, please provide your Anaconda, Spyder, Qt, and PyQt version, a detailed description (preferably with screenshots; you can paste them directly into this chat) of how you're launching Spyder, the behavior you're experiencing, and the the full, exact text of the error message(s), any updates, installations or other configuration/environment changes between when Spyder worked and when it didn't, and the troubleshooting steps (reset preferences, update Spyder, reboot machine, etc)you already tried. Thanks, and best of luck!
