Live USB hanging

Kali Linux 2023 snapshot (USB persistent built directly on USB in QEMU) ASUS VivoBook (16 GB RAM, 19 MB Front Side Bus) I'm trying to set up a Kali live USB to run Fluxion (so I have to use Kali more or less). Problem: kali is booting extremely slow. 10-15minutes from persistence boot menu selection to full boot up once booted up everything works quickly until a new window is opened or new program is started, then everything freezes for 5-10 minutes. sync will not complete until whatever cycle is processing finishes. after new window or program is started completely (5-10 minutes) then everything works quickly until one of the programs begins to process something or a new window/program is started; then system hangs again for 5-10 min. This problem does not occur in LIVE mode, only in persistent live mode. It happens with a clean fresh install directly from the recent snapshot and occurs in both the XFCE and GNOME
