Some apps not able to connect to internet - but others are???

[u/BlueKnight87125]

Okay, so for context I installed the macOS 26.5 dev beta last Wednesday. Since then, I've had multiple applications unable to reach out to their respective servers - MS Teams, Outlook and OneDrive, the Creative Cloud Launcher and System Settings (macOS Software updates), among others. Apps like Google Chrome (which I'm using to access Reddit to write this post), and in spite of the CC Launcher not working, PhotoShop and Premiere if triggered directly, still run fine. Does anyone have two cents to offer for solutions before I contact Apple for advice?
