Hi @Dandent,
Yes, you have a good understanding of what Passphrase is used for and how important it is to remember it.
Do you have the Remember function enabled for the wallet in question in Trezor Suite? If so, try to disable it, disconnect your Trezor device, restart Trezor Suite and reconnect your Trezor device again.
Check that you have the latest Firmware version (2.4.2) from inside Trezor Suite at Settings->Device.
Trezor Bridge should run in the background. It’s the process called trezord. You can check this with Task Manager (Ctrl+Alt+Del).
Please check that you have the latest version of Trezor Suite (21.10.2) and Trezor Bridge (2.0.27). You can check your Bridge version and status at http://127.0.0.1:21325/status/.

That’s correct. A Hidden wallet will need a Passphrase to show its contents. It’s possible to create a new Hidden wallet by mistake, if you enter a wrong Passphrase. However, to be able to work with it later you have to remember that wrong Passphrase too, or it’ll simply be empty and if it’s no funds in there, you can’t lose them either.
So if you have access to all your funds now, and none of the above tips works, then consider to move your funds to another wallet and setup the device with the weird wallet again from scratch, after it’s emptied for funds. You can wipe the device from Trezor Suite.
