[Bug]: Cannot create Desktop Entry after assigning permissions

[IdrisQe]

Describe the bug

I'm running Bazzite 42 NVidia Edition with KDE Plasma 6.4.4, KDE Frameworks 6.17.0, Qt 6.9.2, Kernel 6.16.4-108.bazzite.fc42.x86_64 and Wayland.

I installed Bottles 51.24 from Flathub using Bazaar. It runs fine, and works without issue, except I cannot create desktop entries. I used Flatseal to give permission to:
/var/home/idrisqe/.local/share/fonts (to fix an issue with a game, this permission worked perfectly and without issue)
/var/home/idrisqe/.local/share/applications (as shown in the Flatseal Bottles video guide for Silverblue distros like Bazzite)
/var/lib/flatpak/exports/share/applications (as after the above didn't work I decided to try another place that I know .desktop files reside)
and ~/.local/share/applications (just in case this worked instead for some reason)

Every time I try to add a desktop entry, it just opens the webpage telling me how to set permissions to create desktop entries, which I've already done, so I really don't understand what's going on here.

I've ensured that /var/home/idrisqe/.local/share/applications exists already - in fact some .desktop files already exist there from other programs.

To Reproduce

1. Get versions of programs and system given
2. Make a bottle and install a program to the bottle
3. Give Bottles appropriate permissions
4. Close and reopen bottles, even shutdown or restart system entirely
5. Open Bottles and try to add a desktop entry to the program in the bottle you made

Additional context

Attempting to try again with the terminal open for troubleshooting, no error is printed when the .desktop file creaton fails.

Also, here are all the flatseal permissions, in case something else is missing:
