Try connecting to a USB wired keyboard?

For the Apple Macs that are USB-C only, you’ll probably need a USB-C to USB-A adapter, or a dock with USB-A sockets, to make that connection with the commonly-available keyboards and mice. The Mac mini M1 2020 has USB-A sockets, so this swap is feasible without adapters.

A reset here is a bit involved: Revive or restore a Mac with Apple silicon with Apple Configurator 2 - Apple Support

It may be that one or the other or both devices need a fresh battery charge.

Plug your keyboard into the Mac mini as if you were charging it. The mini should connect to the keyboard and allow you to login. The mouse may require time on a charger as well.

But is there any other way to connect with Mac mini M1 than with a wired mouse or keyboard. I have only Bluetooth keyboard or mouse?

Apple wireless keyboards and the Apple wireless trackpad can operate as wired, using a Lightning cable.

It’s also used as the re-pairing and the re-charging mechanism.

Set up your Magic Keyboard, Magic Mouse, or Magic Trackpad with your Mac - Apple Support

Recharge the built-in battery in your Apple keyboard, mouse, or trackpad - Apple Support

Or borrow or buy wired devices, particularly if Bluetooth is problematic for whatever reason.
