Based on NUCLEO-F446RE target usage expecting to rely on StdPeriph firmware you should have a C:\Users\AppData\Roaming\Ac6\SW4STM32\firmwares\STM32F4xx_DSP_StdPeriph_Lib_V1.8.0 directory extracted from stm32f4_dsp_stdperiph_lib_v180.zip file.
Do you have such .zip file ? If yes please could you have a try to extract it by yourself. Once such done please have a new try to create a project (takes care .zip file & extracted content are required to enable firmware package automated detection). On my side such is working fine with latest version you have (no need to unzip by myself).
According your provided .log analysis sounds some toolchain extraction issue has happened too at first product launch. This issue plus lack of extracted firmware content may be related to some disk space issue ... please double check.
Feel free to share back !
