fish: Job 1, 'o/blink/blink -eC ./alpine-mini…' terminated by signal SIGKILL (Forced quit)

Steps to Reproduce:

1. Download the alpine-minirootfs package and extract its contents into a designated folder.
2. Use chroot to switch into the extracted root filesystem.
3. Install the .NET runtime using the official installation script provided by Microsoft.
4. Exit the chroot, execute .NET runtime using the command: o/blink/blink -eC ./alpine-minirootfs/ /root/.dotnet/dotnet --help.

Additional Information:

• Using the -m argument with the command leads to a different kind of crash, specifically a SIGSEGV (Segmentation Fault) rather than a SIGKILL (Forced Termination).
