libtouchgfx-float-abi-hard.a cause build error in STM32CubeIDE

[STran.2]

I followed instrunction in this online workshop STM32 Graphics Workshop - 10 TouchGFX lab temperature sensor display https://www.youtube.com/watch?v=rYrRjXyAYvs&list=PLnMKNibPkDnGNY9Ny4FWpM5bgC3b4XdbN&index=10

When I get to (minute 18:30) the step build in STM32CubeIDE I get this error list below. Please help.

17:31:33 **** Incremental Build of configuration Debug for project STM32H7B3I_DISCO ****

I did not try anymore to solve the error but I started a new project following the indication of the workshop with last firmware repository 1.08 , touchgfx 4.15 and idea 1.5 and it works. Cannot set the same clock setup.
