ERROR: Index p_type_a = 2712273640 is out of bounds (Variant::VARIANT_MAX = 38)

just cloned the master repo at this commit
https://github.com/godotengine/godot-cpp/commit/86703055894cb2555f0ec704eff11e3c1c81a5d3

and tried to compile and run with gdextension example, compiled with no errors, but when opening the project in godot, this error gets thrown and crashes

```
ERROR: Index p_type_a = 2712273640 is out of bounds (Variant::VARIANT_MAX = 38).
at: get_ptr_operator_evaluator (core/variant/variant_op.cpp:1051
```

but older commits work fine, the submodule used in actual gdextension works fine
