Raspberry Pi 4 extremely slow

Hello!

I just installed LibreELEC on my brand new RbPI 4 4G, and the interface is extremely slow. It takes something like 20-40 seconds to go back. Not sure why this is.

I checked the usage of the ram and CPU but its not even at 10%, so that's not it...

Any help would be great as this makes it really unusable...

151° Fahrenheit does not seem very high (I am scanning my library). But I just checked with another SD card, and it works fine. Thank you pasty1969 !
