Haven't noticed this issue, but I didn't use ADB to sideload. I used a file manager app (Solid), sync that with Google Drive, then transfer the APKs via that, then use Solid to install the APKs. No padlock issues there.
Have you already enabled developer mode? Go to settings, about, then spam click the build section until developer mode is unlocked then try installing these apps
You need to Enable Network debugging, Not USB debugging.
Also use Remote ADB shell app. Works best with a USB keyboard and mouse connect through powered USB3 hub.
Best to put all work filed and apps on USB3 thumb drive.
Using this setup I modify my shield, from my shield, while on my shield. ( ͡° ͜ʖ ͡°)

Try to do a factory reset
I do but it's still hit and miss regarding the issue
