Unable to start WebApps having a space in their name (Ubuntu)

I am running WebCatalog on Ubuntu.
I am able to run without problems all the apps that have no spaces in their names (e.g. Gmail, ChatGPT, Overleaf).
However, if I try to run an application that has a space in its name (e.g. Google Calendar or Google Drive), it does not start.

If I try to run it from terminal with ./Google\ Calendar (from the ~/.webcatalog/Google Calendar directory) I get the following output:

LaunchProcess: failed to execvp:
/home/alessandro/.webcatalog/Google
[906685:0121/155832.443998:FATAL:zygote_host_impl_linux.cc(201)] Check failed: . : Invalid argument (22)
Trace/breakpoint trap (core dumped)

It seems that it takes only the first part of the name of the app (Google), ignoring the space and everything that comes after.

Is this a bug? Is anyone else experiencing this issue?

It all works fine for me - Fedora 40-42. I just checked the (xfce) launcher, and it shows:

“/home/user/.webcatalog/Google Calendar/Google Calendar”
