I need any project even empty, as an example stm32f103c8t6. Which will be compiled and debugged. In the future I will change it. At what stage is the permission to download and update the firmware?
If you don't have a connection you will be asked if you would like to set up a connection when you start a new stm32 project. Are you able to download any firmware at all? Do you have the correct repository pointed out to let CubeMX know where to find the firmware you (potentially) already have?
It turned out that your linker does not like Cyrillic names in the paths. One of the folders had a Russian name. I think other users will have similar problems. Warn them. thank
