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?

Where is the 940GB of empty space relative to the Mac partition?
If it is immediately after the Mac Partition in a clockwise direction, you should be able to grab the handle in the Partition pie and rotate around to the end of the free space. That will add the free space to the Mac partition.
Partition a physical disk in Disk Utility on Mac - Apple Support
You may have to do that while started in Recovery.

There are some instructions for erasing the drive in the Recovery article, if needed.
The 940 GB isn't even visible in the disk utility. I can see the total disk is 1TB. There is a graph in which only 60GB is visible.
Go to View->Show All Devices
Select the whole drive, not just the volumes in it, and post a screenshot
Thanks for following up with the solution. Sorry I missed that option.
