Esri doesn't offer technical support outside of licencing and installation for students/personal users.
The fastest way to fix this issue will be to identify when it happens i.e. doing a certain task, or after a period of use. What error message do you see, if any. Then users can suggest specific reasons why this is occurring.
Without that here are some suggestions:
Check system requirements.

If you computer does not meet the specs, or you are running other software (including additional instances of ArcGIS Pro), you will have a bad time.
Don't click while things are loading/processing
When ArcGIS Pro enters a processing state (circle spinning next to mouse) trying to create new interactions can cause it to go non-responsive. Generally ArcGIS Pro is a lot better with this than ArcMap was traditionally.
Don't use cloud storage
Students often use cloud storage. Saving ArcGIS Pro Projects and geodatabases to a cloud storage drive is a bad idea. You should save them to a local drive and copy across manually once finished, to store a backup.
This is because of the number of files that are constantly being read and written going bad with the sync process.
Anti-virus
Same reasons as cloud storage, anti-virus can interfere with the large volume of files. Mark ArcGIS Pro as a safe application.
Check temp storage / workspace geodatabases
Again should be local and accessible
Check spare space/memory on computer
