Bindiff unable to process statically linked binaries exported with BinExport from Ghidra (flow graph already attached error)

**Describe the bug**
Bindiff is unable to process statically linked binaries exported by Ghidra with BinExport.

I have not tried BinExport with IDA.

**To Reproduce**
Steps to reproduce the behavior:
1.

**Expected behavior**
A clear and concise description of what you expected to happen.

**Screenshots**
A binary like this:
openssl: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, BuildID[sha1]=6143bc37788cd04527de063e16c35627b1610ea2, for GNU/Linux 3.2.0, not stripped

Will result in an error like this:
terminate called after throwing an instance of 'std::runtime_error'

what(): AttachFlowGraph: flow graph already attached 00401000

**Environment (please complete the following information):**
- Ubuntu 23.10
- Locale: US English
- Disassembler and version: Ghidra 11.0 with BinExport 12 with BinDiff 8

**Additional context**
I have tried this with multiple statically compiled binaries and it seems to fail with the same error. Binaries that aren't statically linked do not have this error.
