SFTP arraycopy error on authentication

Please add #com.intellij.ssh and #com.jetbrains.plugins.webDeployment to Help | Debug Log Settings, restart the IDE, try to connect again and then share the generated logs (Help | Compress Logs and Show in Finder).

note: I stripped the server address stuff and private from the log

the machine is a new MacBook Pro 2019 8 Core with 16GB RAM

Is this what you need?

Hello, just following up on this.

Does anyone have any recommendations on how I can fix this error? I've tried reinstalling, refreshing the keys, resetting the known_host file to name a few solutions.

I'm stuck too, seems like rolling back to an older version of the IDE may be the answer.

Hey, thanks Jon... it feels better knowing I'm not the only one. :-)
