idleassetsd massive memory leak on macOS Sequoia 15.2

I'm on macOS 15.2 and today I've just discovered a very bad habit for idleassetsd: a massive memory leak when working offline. My situation is: screen savers disabled, static background, and working mostly offline. I restarted my MacBook Air M1 and opened Activity Monitor in the memory pane; idleassetsd started popping out with a very limited usage, but then it grew up and after a few minutes is now using 21 GB of memory (mostly swapped)! While writing this few sentences, the number has already changed to 23.00 GB. This happens when idleassetsd is offline, so when my machine is not connected (really offline) or when I block it to reach the network (I'm using TripMode, but any other technique shows the same behavior). What's happening is that in the next 30 to 60 minutes my hard drive will be fully used, and my Mac will crash and reboot. If I go online the memory usage stabilize (but doesn't decrease if I don't reboot), but then the software downloades a lot of gigabytes (like described in other posts like idleassetsd going crazy ). Just for completion: the software is also writing gigabytes and gigabytes on my SSD, both when online and offline, consuming my SSD. I've tried all the solution found to disable it since the disk and network usage is a well known bug from macOS 14, while it's the first time I read about the memory leak, but none was working. Thank you all for any idea or suggestion. ps: now 25.7 GB and counting....... Update 1: I've reported it to Apple. Update 2: What I've tried to solve the issue so far: - countless reboots (forced and "natural") - removed files in the /Library/Application Support/com.apple.idleassetsd folder (and rebooted) - selected the Sequoia screensaver for all accounts - standard, not animated (and rebooted) - disabled the screensavers activation from all accounts (and rebooted) - enabled the Sequoia background on all accounts (and - guess what? - rebooted!) - killed the process - deeply searched on Google, Reddit, StackOverflow and other resources ## Logs The errors log when working completely offline is a repetition of the following block: errore 07:39:57.483776+0100 idleassetsd Connection 2058035: received failure notification errore 07:39:57.483992+0100 idleassetsd Connection 2058035: failed to connect 1:50, reason -1 errore 07:39:57.484042+0100 idleassetsd Connection 2058035: encountered error(1:50) errore 07:39:57.487919+0100 idleassetsd Task .
