There can be any number of reasons for lsass.exe to grow in size on any Windows OS Version. If you are saying that this memory grow has started after a security update, then that issue would have to be troubleshoot for that security update as it would be unique to that security update.
The issue that caused lsass to consume more memory in the March update has been fixed so this memory leak issue should not be an issue any longer. The memory leak from March would not really be noticeable on a workstation as the amount of service tickets requested would typically not be that great as compared to the typical uptime of the workstation and amount of RAM on the system.
If you are seeing an issue with lsass memory consumption going on and never coming down, we in support would need to collect data and see what is happening here. As of right now 7/10/2024 we are not aware of any lsass.exe memory leak within the OS because of a monthly cumulative update.
One last thing to keep in mind that anything external to lsass could be the cause for it to consume more memory, and if that application fails to free the memory then lsass.exe is just left holding the bag. You might want to think about any other recent applications additions or changes or upgrades on workstations that might actually be causing the issue. Then remove them for a time and see if the memory consumption still happens. The first things I would look at as possibilities is any security software (endpoint management, anti-virus, firewall, etc) a lot of these types of software do have hooks into lsass.exe.
