Got it back now, deleted app and re-installed and it brought up my wallet without needing to plug in the device, maybe it wasn't fully deleted but the link got corrupted instead? don't know.
I checked apps in settings and its there with todays date so not sure what happened there, some sort of memory file remained in place maybe, dont have any reason to be suspicious did check was correct Trezor webpage for the download.
It is not uncommon for a program to have plugin problems, corrupted files, etc...
Trezor has a folder that is installed on your computer. If you want to check it out, here's how:
Press the Windows + R key
Then use the command: %appdata% (copy, paste and Enter)
The path will be: AppData\Roaming\@trezor
That's where the data is, and Trezor just retrieved that data again
Even if your wallet appears, you will notice that you will only be able to access your funds using the device
