[Users] Error with the Cactus Tutorial

Hello, I am writing to seek your assistance regarding a sudden error I encountered while running a cell in the Cactus Tutorial. The following command was functioning correctly until recently:

%%bash ./simfactory/bin/sim build -j2 --thornlist thornlists/einsteintoolkit.th

The error is:

collect2: fatal error: ld terminated with signal 9 [Killed] compilation terminated. make[1]: *** [/home/andre2mila/Cactus/lib/make/make.configuration:150: /home/andre2mila/Cactus/exe/cactus_sim] Error 1 make: *** [Makefile:265: sim] Error 2

If necessary, I would be open to having my tutorial reset.

Thank you for your time and assistance,

Andrea.
