Windows 10: UWP App Icons missing from Taskbar, also unable to remove said icons or pin them back after...

Everything was normal and I powered up my laptop. Once I log in I notice that the icons for UWP apps except for Your Phone that are on my taskbar are missing. I thought unpinning them would solve the problem, but when I right click the icons, the only thing that shows up is "Unpin from taskbar" and nothing else, which is odd, and when I try to unpin them, nothing happens. They just stay there and won't go away. I've tried running Disk Cleanup to see if it was an issue with the old icons conflicting with the new Fluent Design icons, but to no avail. I'm not running an Insider Build either, just the standard version 1910


I've provided a picture of the issue, it's really strange how this cropped up out of nowhere and I have looked and asked around in other places and have gotten nothing out of it. The icons in order are Microsoft Store, Weather, and Mail


I tried reinstalling Weather and Mail, and that did remove the icons from the taskbar, but now I cannot pin them back to the taskbar for some reason which is even weirder.

If anyone knows how to fix this issue, please let me know as this is annoying as these 3 applications are ones that I use a ton.

UWP icons dark on taskbar

and wanted to post the solution in case anyone has this issue.

It was Start10 causing the issue. You can pick different styles of Start Menu in it -- Win7, Modern, and Win10 Styles. But Win7 and Win10 Styles have different icons for UWP apps. So since I had pinned the UWP apps to the taskbar while running in Win7 style (dark icons against light backgrounds), you could barely make them out. You need to be running in Win10 Style when you pin the apps to the taskbar.

Fix was really simple:
- unpin the UWP apps from the taskbar
- right-click Start10 start icon, 'Configure Star10...' and pick the 'Windows 10 Style'
- re-pin the UWP apps to the taskbar
- switch back to 'Windows 7 Style'

 

Unable to Pin Firefox icon to taskbar

Yupp, this Pin and Unpin from Taskbar are missing on my context menus. I have it for Thunderbird though





Mais stands for More, Afixar em Início stands for Pin to Start, Afixar na barra de tarefas stands for Pin to Taskbar

 

Icons of UWP/Metro apps not showing in taskbar





Icons of UWP/Metro/Modern apps (first gap in the image is Edge, second (the active app) is mail, third is Twitter) are not showing up in the taskbar, nor when they're pinned, nor when they're opened. Icons of classic desktop (Win32) apps are visible. Icons
from the right to PowerShell are pinned, from Slack to the right are just opened.

I've tried several reboots, upinning and re-pinning the apps and a script suggested here: Icons pinned to task bar are not displayed properly on Windows 10.,
but my problem isn't solved. Any ideas?
