I get the following when I start julia from the repl window in Juno. I do not get the error when I start julia without juno:

Weird. What Windows version are you running?

Disabling the powershell wrapper in julia-client’s settings should work around the error though.

So, the problem was:

Source file 'C:\Windows\TEMP\fjxbgjrb.0.cs could not be found

The reason was C:\Windows\Temp was read only for some reason. I made it r/w and the problem goes away
