I can't find TrueStudio in Toolchain/ide


Hello @kuslu.1 and welcome to the Community :)
Since STM32CubeMX 6.6.0 released: TrueSTUDIO, System Workbench for STM32 (SW4STM32), and the GPDSC option are removed from the list of supported IDEs in STM32CubeMX.
It's recommended to use STM32CubeIDE (an all-in-one multi-OS development tool).
Note that TrueSTUDIO is not recommended for New Designs (NRND).
