Option 'load' registered more than once!

[IMMORTAL23]

Description:
I'm running into an error when trying to use the opt command. All the passes in the repo work fine. But when I wrote and ran my own pass code using MBASub.cpp as a template and this error produced.

I've checked my command line arguments to make sure I'm not specifying -load multiple times and my code only change the name and runOnBasicBlock function in MBASub.cpp , so I'm not sure what's causing this error. Can anyone help me troubleshoot this issue?

Steps to reproduce:

Run the opt command with opt-14 -load-pass-plugin ./lib/libIndirectJmp.so -passes=indirect-jmp -S ./inputs/input_for_mba_sub.ll -o out.ll
Observe the "Option 'load' registered more than once!" error message
Expected result:
The opt command should run successfully with the specified options.

Actual result:

opt-14: CommandLine Error: Option 'load' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
