RAM usage is much different with compiler and inspect

Hi, all.

I am using PlatformIO for the esp32cam project with ArduinoFramework. When I see the RAM usage by PIO Inspect, it’s much different from the compiler shown.
Complier shows me 13.8% of RAM, but Inspect of PIO shows 100%.

Why those are much different? I am not sure because I think I didn’t use much RAM.
Does anyone have any idea?
