After fresh install of CyberPanel and wordpress,
I have increase file size in PHP as well.
I am trying to upload plugin larger than 1mb and receive error 500, if I upload tiny plugins its working fine.

The only work around so far working for me is uploading plugin through file manager and then activate it through wordpress dashboard.

Check error logs from the server, also enable debugging in wordpress and check the debug logs.
This should point you in the right direction.
