Did you solve the problem? I had a same issue and am writing for helping others.

My issue is that there are some garbase yaml file in "%USERPROFILE%.dapr\components"

• For Linux/MacOS: /$HOME/.dapr/components
• For Windows: %USERPROFILE%.dapr\components

I guess when I execute dapr init without --slim, it made some components yaml file. So, I deleted all of yaml file in that path, dapr work normally.

I Hope it helps you.
