Fcitx 5.1.6 crashes on uv_poll_start() on OpenBSD 7.4 current during dbus connection

[ZhanYF]

Describe the bug Fcitx 5.1.6 crashes instantly on OpenBSD 7.4 during dbus connection due to problem with uv_poll_start()

To Reproduce Steps to reproduce the behavior:

1. Run fcitx5-config-qt
2. Click Run fcitx 5
3. Segmentation fault (core dumped)

Note that fcitx5 can be started, but if fcitx5-config-qt attempts to connect to it, it will crash.

Expected behavior fcitx5 should start normally and allow the user to configure it.

Desktop (please complete the following information): Seems not DE related, same behavior on KDE/Mate.

Additional context fcitx crash log:
