Terminal stop launching in Double Commander after Catalina 10.15.1 upgrade
Had the same issue. Solution that worked for me:


In DC go to Configuration -> Options -> Terminal
In section "Command for just running terminal:" was Command /Applications/Utilities/Terminal.app
Rewrite it to the /System/Applications/Utilities/Terminal.app
Save changes and now when you press Fn + F9 terminal will open in current directory just like before
