Dealing with a difficult team member: Need advice

I am currently facing a challenging situation at work and could really use some advice from those with more experience. I’ve recently joined a new project which one of the older team member is handling. However, I’m experiencing some serious issues with his behavior.

He frequently blames me for things that haven’t been communicated properly and acts as if he is the boss, which isn’t the case. This has made me feel undervalued and unsure about my own abilities.

Is this a common issue? How should I handle this situation? I’m concerned about how it’s affecting my confidence and performance at work.

He even told me that I don’t clearly know what is expected from me and I don’t know how to do the tasks better.

Any suggestions on how to address this would be greatly appreciated. Since he is much more experienced than me I don’t know what to do.
