WORKAROUND:
Now if you get this error the workaround is to disable capnproto (which you won't need if you don't use the load/save search function. I integrated many games without this function)

In CMakeLists.txt after line 260 simply write:

set(CAPN_PROTO_FOUND OFF)

relaunch make

This wouldn't be related to the new cores right? Maybe updating the third party libs (capnproto, pybind11, etc) could be beneficial

This works. Thank you very much.

I am not sure, but I think we should disable this feature by default while we figure it out because I fear many users might get this blocking issue for a feature 99.9% won't use. I will submit a PR to disable capnproto by default
