Empty string passed as argv[1] if no options provided, making Palia Launcher misbehave.

I'm trying to run Palia's launcher, a free-to-play game currently in open beta. The trouble is that Heroic tries to launch to launch it like that according to the log file:

Unfortunately, this application misinterprets an empty string as argv[1] as a command line parameter, tries to parse it as a command, and just exists. Sad trombone.
