Again the message tells you exactly what the problem is. And since it happened again it is likely one of many problems.
Missing venv folder was first sign of something going wrong. I will assume the most probable reason for missing files and folders is you deleting them. Or maybe trying to move project from one place to another without taking all the required files and folders with it.
Or, I might rather ask... Did you create a new project in PyCharm with virtual environment in the first place?
Has the project ever worked (script executed successfuly) before the errors started? If yes, what changes did you make?
