Hello,
If you have newly enrolled in IGNOU for July Session, then you can find the assignments from the official website at https://webservices.ignou.ac.in/assignments/ , as you haven't mentioned your course code, hence I couldn't confirm if the assignments for July session has been uploaded or not, but even if it hasn't it will get updated here only, you will also find the earlier assignments in case you're not newly enrolled.
