Issue with I/O usage

About a couple of month ago after my yearly subscription had expired and it went into a grace period, ever since then when I open up Illustrator or Premiere Pro, the I/O usage on my system spikes and sits on a constant range of 100-300MB per sec being used up by the app. This happens with the app even when it's just open and no file is loaded. This does NOT happen when Photoshop is open. What is going on here? After I renewed the subscription, this stopped for a few days and now it's back again. This is annoying as hell as it spins up my system fans trying to cool the board. Note: this is NOT Disk I/O nor is it Network I/O, this IS system I/O being caused by these 2 apps. Screenshot below.

Update: I signed out from CC and then opened an AI file, it opened the file in the background and prompted the CC login window upfront. There is NO I/O usage happening till the moment I sign in. As soon as sign in happens, the I/O usage starts hitting the above mentioned levels constantly even when zero activity on AI.
