LSAP usage is very high and is causing crashes

Question

Hi all,

Just needing a bit of help. My Windows 11 dell inspiron 7591 2in1 (i7) has been having issues with LSAP (lsass.exe) using an inordinate amount of memory. Once it starts up it just keeps usind more an more memory until the system crashes.

So far I have done;

a couple of clean installs - the problem comes back as soon as I unpause auto updates. Unfortunately as windows now wont let you install selective updates I'm not sure which one is causing the problem.
file system scan with bit defender for viruses
ensured my drivers are up to date
Run a DISM restore heath
Run chkdsk
Turned off BOTH File encryption and Device encryption
Run sfc /scannow
Hardware scans with Dell support.

So far no luck so any pointers would be appreciated. Apparently problems like this are usually caused by a driver error but I'm not sure which driver is at fault.

To receive assistance from Dell chat support, they need to verify the warranty status and ownership. Then you must troubleshoot with them. Click the "Get Help Now" icon on the right to start a live chat session. If already out of warranty, click here for the Dell out of warranty offering.

@DELL-Jesse L​ Oh I am out of warranty, I was looking for community support. I have since done a clean install with Windows 10 which has worked perfectly showing there's no hardware issue.. SO there is a conflict between Windows 11 and Dell drivers (I installed every single one from the support assist and the website to no avail.) I had assumed Dell would be interested to know of the conflict but I guess once you have our $$ you don't care about consumers.
