Hi, um, the bootloader is the thing that takes time. If you remove USB 5V and just use the VIN the bootloader is bypassed. Then it startups instantly.

Is there any influence from the micropython since we need import some libs first?

Only the bootloader takes any noticable time. Everything else cost less than 1 ms to boot up.

In your scripts, make sure to load the camera auto gain configs and such from what you had previously to get it up and running in 1-2 frames versus waiting a few seconds.

Also if the Flash file system is corrupted it takes time to create a fresh fs.
