I tested Asahi Linux on my M1 Mini. Now I want to go back to macOS but that doesn't work. The Mac partition is 60GB in size (to small to instal macOS) and 940GB of empty space that I can no longer approach.
How can I format the disk in such a way so that I can install macOS again.
Anyone an idea how I can do that?
Sincerely

You always have the very simple fallback option of using another Mac running macOS 10.15+ to "Restore" the firmware of this Mac which will do all the heavy lifting for you (or have an Apple Store or AASP assist you with the firmware "Restore"):
Revive or restore a Mac with Apple silicon using Apple Configurator - Apple Support
You can also try asking on the Asahi forums for assistance.
While I have worked with drives and partitions a fair amount, I rarely use macOS to manipulate them, nor do I normally customize a macOS setup since macOS doesn't like any surprises from the OS defaults. While macOS provides some of the same utilities as used with Linux, the macOS versions tend to be very old & outdated with far fewer features and abilities. Very few contributors on the Apple forums are familiar with dealing with the more complex partition manipulations and even fewer know much about the M1 Mac drive layouts. Unfortunately the one contributor who is a macOS partition expert, LonerT, has not been seen on these forums for quite some time.
Please let us know how it works out as the information will help us to help others in a similar situation.
Good luck.
Here is how it looks like:
When i enter the instruction "diskutil list internal" in the terminal in the picture you can see how i looks like.
Anyone a idea how i can solve this problem??
Thanks for following up with the solution. Sorry I missed that option.
Format m1 disk totally
