Memory Leaks caused by Web Interface?

What is the problem?

Last year I had issues with memory leaks, In the end, I thought it was my Antivirus Bitdefender and MJPEG streams, but now I’m not sure.

What did you already try to solve it?

Last year, I reinstalled Windows to fix this issue and it went away. I've reinstalled a few times since and it's been fine until recent.

Have you tried running in safe mode?

Not yet.

Did running in safe mode solve the problem?

Additional information about your setup

OctoPrint 1.7.2
Python 3.7.3
OctoPi 0.18.0

Microsoft Edge 96.0.1054.43 (64 bit)
Windows 10 Pro (64 bit)

The hard thing about this issue is, it's hard to tell what's causing it (having a lot of things open (CAD, PrusaSlicer, browser, etc). It seems to be Octoprint related this time.

I'm in contact with Bitdefender right now.

Have you tried another browser?

I haven't yet.
Last time where the issue seemed to be only MJPEG based, Using multiple browsers didn't help, the issue persisted - hence why I assumed it was an issue with BitDefender.

Right now, I'm leaving the Octoprint interface open and waiting for the RAM to increase. Just clicking round doing things in it. No MJPEG, standard background apps open.
RAM hasn't increase in last few minutes yet.

Next, will test safe mode, then another browser - probably Firefox.

This issue is incredibly intermittent.
Using normal mode. Octoprint in Edge
