Yarn Problems - Been trying to get my server back up and running but Yarn seems to be having some issues

This image contains the 2 errors - That I am currently facing. I’ve tried clearing cache and unfortunately that hasn’t worked. So if anyone could help me in this situation. Please feel free to contact me.

Try delete server cache then reupload webpack and yarn. Then try to start again. If u move server from a hosting platform to your localhost or from localhost to server ,this happens frequently, sorry for my bad eng.
