Hi,@M Faheem Akhtar . Welcome Microsoft Q&A. Is there any update to the question? Did Viorel's answer solve your problem? If so, you could accept it as the answer. It's helpful for community members with related questions.
Probably Visual Studio has an issue, which can be reported using the “Send Feedback” command from HELP menu.
Try the updated latest Visual Studio (today it is Visual Studio 2022 17.7.4). Probably the Preview version does not have to be uninstalled.
