New issue by kawaiiamber on void-packages repository

https://github.com/void-linux/void-packages/issues/27771

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  Void 5.9.16_1 x86_64-musl GenuineIntel notuptodate rrnFFF
* package:  
  ``flatpak-1.8.4``

### Expected behavior
Execute application

### Actual behavior
It seems to fail to be able run from some permission issue?

### Steps to reproduce the behavior
Follow setup guide for VOID as seen [here](https://flatpak.org/setup/Void%20Linux/).
```
# xbps-install -S flatpak
$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
```
Install an app
```
flatpak install flathub com.discordapp.Discord
flatpak install flathub com.valvesoftware.Steam
```
This was a while ago, but I believe I did some variable overrides.
```
sudo flatpak --env GTK_IM_MODULE="fcitx" --filesystem=$HOME com.discordapp.Discord
```
Attempt to run the app
```
[amber@otaku ~]$ flatpak run com.discordapp.Discord
bwrap: Can't mkdir parents for /run/host/fonts: Permission denied
[amber@otaku ~]$ flatpak run com.valvesoftware.Steam

Bad item "/home/amber" found in filesystem overrides
Please see https://github.com/flathub/com.valvesoftware.Steam/wiki#i-want-to-add-external-disk-for-steam-libraries
```
I was told to report issue to distro first, closest bug I can find relating to this is [here](https://github.com/void-linux/void-packages/issues/11456). Though, I don't want to re-install VOID. I'm not sure how to revert / purge changes I did with flatpak. I tried
```
# xbps-remove -R flatpak
# xbps-reconfigure flatpak
# xbps-install -Sf flatpak
```
