Slow boot after update to Monterey

Hi there,

Just updated my build to Monterey, with OC 075. For some reason, the boot time has dramatically increased as compared to what I had with Big Sur. The system spends considerable time there with a lot of disk activity at that particular point:

com.apple.xpc.launchd <Notice>: Doing boot task: bootroot.

After 30 seconds or so, the process proceeds normally.

Any idea as to what may cause this delay ?

Thanks in advance.

My build:

• CPU: i5-9600K
• GPU: Radeon RX 5700 XT
• RAM: 32 GO
• Motherboard: Asus Prime Z390-A
• Audio Codec: Realtek ALCS1220A
• Wifi/BT Card: Fenvi T919
