[Bug] IDA 9.1 fail on non-decompilable binary. #450

Description

Hi!

On this code on compat.py (from libbs):

@execute_write
def get_decompiler_version() -> typing.Optional[Version]:
    wait_for_idc_initialization()
    try:
        _vers = ida_hexrays.get_hexrays_version()
    except Exception as e:
        _l.critical("Failed to get decompiler version: %s", e)
        return None

    try:
        vers = Version(_vers)
    except TypeError:
        return None

    return vers

return None in IDA 9.1.
Making this error in controllers : CRITICAL | 2025-08-26 17:59:51,526 | binsync.ui.config_dialog | Error connecting to specified repository: '<' not supported between instances of 'NoneType' and 'Version'!

the problem come from : _vers = ida_hexrays.get_hexrays_version() return None in ida 9.1... (yohoo Hexrays API update every 1day)

Steps to reproduce the bug

Run binsync in IDA 9.1+

Environment

binsync 5.7.8 /home/tpo/Bureau/binsync
libbs 2.16.2

Additional context

Do i need to create issue on libbs also?
