Guppy initialization fails, unexplicably

Yesterday megalodon stopped working, and now consistently gives the error:

ERROR: Guppy server initialization failed. See guppy logs in [--output-directory] for more details.

However when I run the guppy server initialization command in the log file, it starts up just fine.

These are the commands:

megalodon \
    example_data/ \
    --guppy-params "-d ~/asmetha/rerio/basecall_models/" \
    --write-mods-text \
    --guppy-config res_dna_r941_min_modbases_5mC_CpG_v001.cfg \
    --outputs mods \
    --reference ~/compdir/refgenomes/chm13_V2/chm13v2.0.fa \
    --mod-motif m CG 0 \
    --devices 0\
    --processes 10 \
    --guppy-server-path ~/compdir/guppy/v6.3/ont-guppy/bin/guppy_basecall_server \
    --output-directory megalodon_output_rerio_baseenv

Output:

This is the command in the log.txt:

/home/cog/cvermeulen/compdir/guppy/v6.3/ont-guppy/bin/guppy_basecall_server -p auto -l megalodon_output_rerio_baseenv/guppy_log -c res_dna_r941_min_modbases_5mC_CpG_v001.cfg --quiet -x cuda:0 -d ~/asmetha/rerio/basecall_models/

This works, with only output: CRASHPAD MESSAGE:

And when I remove the --quiet tag:

I tried a lot (new conda environments, reinstalling megalodon, different guppy versions), but I really can't figure out why it isn't working, so any help is really appreciated.
