** Autobrr Version**
1.52.0

Describe the bug
I'm running autobrr on Docker, on Ubuntu Linux, on an ARM64 SBC, using a shell script in an external filter to calculate free space and fail the filter if free space < 100 GB. The external filter is failing with the logged error:

(Television) external filter check error error="error executing external command: fork/exec /config/freespace.sh: exec format error"= method=CheckFilter module=filter stack=[{"func":"(*service).RunExternalFilters","line":"564","source":"service.go"},{"func":"(*service).CheckFilter","line":"451","source":"service.go"},{"func":"(*service).processFilters","line":"205","source":"service.go"},{"func":"(*service).Process","line":"182","source":"service.go"},{"func":"goexit","line":"1223","source":"asm_arm64.s"}]

The script is set as executable and I've set CHOWN to assign the script with the container's PUID / PGID. I can run the shell script successfully when logged into autobrr's container.

To Reproduce
Run:
/config/freespace.sh as external filter.

Result (when executed manually, in container):
More than 100 GB of storage space is available. Free Space: 355.5G GB

Expected behavior
Expecting successful execution of shell script and filter.

Additional context
Shell script:

set -e

reqSpace=10000000 # 100GB
SPACE=$(df "/Media" | awk 'END{print $4}')
if [ "$SPACE" -le $reqSpace ]
then
  SPACE=$(df -kh . | tail -n1 | awk '{print $4}')
  echo "Less than 100 GB of storage space is available."
  echo "Free Space: $SPACE GB"
  exit 1
fi

if [ "$SPACE" -gt $reqSpace ]
then
  SPACE=$(df -kh . | tail -n1 | awk '{print $4}')
  echo "More than 100 GB of storage space is available."
  echo "Free Space: $SPACE GB"
  exit 0
fi
