Troubleshoot Windows Apps are greyed out with an exclamation mark icon

Hello,
I'm not sure if this other problem is related with the previous, on the Windows start menu some applications are "black" and cannot launch

hello JB007, after 4, 5 days my windows update start to work and I made the update smooth.
After "over thinking" a lot I remove all my security softwares and, reset some settings on the system with this tool: "Windows 10 manager".
this is a trial software that tweak, optimize, fix and reset your windows Speed Up & Optimize Windows 10 | Tweak Windows 10 – Yamic Soft
in my situation, I just hit fix button and after restart my laptop the updates run smooth and come back to normal.

**Do a restore point first**
cheers.
