First time using STM32CubeIDE and I'm following the tutorial here: https://www.youtube.com/watch?v=hyZS2p1tW-g No issues until I attempt to edit the main.c file but it doesn't exist. Can someone help? I've attached a screenshot if hat helps.

Did you choose File > New > STM32 Project?

Did you choose a simple path name (no spaces, no umlauts, only plain ASCII) for your CubeIDE installation and your project?

It appears to be a something strange in the IDE. Saving is not possible as is to create the main.c file. The fix is to click on any pin, change it to Input or output, then change back to its original state and then I can click save to continue.
