I’m a great dev but I literally turn into a vegetable during technical interviews. I need help at this point.

Honestly, I’m at my breaking point. I’ve been a dev for 4 years, I crush my tickets at work, and my manager loves me. But as soon as I jump on a Zoom call for an interview, my brain just stops functioning. I had a technical round yesterday for a Senior role and it was so embarrassing. I knew the answer to the LeetCode medium, but I just couldn't explain my thought process. I was stuttering, my palms were sweating, and I totally forgot how a basic hash map works for like two minutes. I felt the interviewer’s interest go from a yes to a big no in real time. Does anyone else deal with this? How do you stop such "interview blackout" from happening? I feel like I’m going to be stuck at my current job forever.
