So it looks like a build issue.

The possible candidates to check would be https://github.com/bitcoin/bitcoin/commit/140f0d89bf6885ad3746a304d9b575ad30ec1501 or https://github.com/bitcoin/bitcoin/commit/e563cb5c60629b2a64c6672a0868d879adf258d7

Reverting #31849 fixes the issue.

Looks like it's fixed by removing the workarounds on the oss-fuzz side: https://github.com/google/oss-fuzz/pull/13187.
