Unable to break blocks while walking

Unable to destroy/attack while walking

What I expected to happen was...:

What actually happened was...:
I can't destroy/attack while Walking, even though I can destroy/attack while sprinting or staying still

Steps to Reproduce:

2. Try to destroy/attack blocks

I have this bug in all versions of minecraft
