How to fix Malwarebytes unable to connect to service error?

Issue: Hi, I have read a lot of good Malwarebytes reviews, and I decided to try it. However, as soon as I installed it and performed a full system scan and shut it down, I could never open it once again, since it returns the “Unable to connect the service” error. Could you help me with this, please?
