Please add a description of the bug and include a sample to reproduce the problem, thanks.

Description:
Environment:
Spring Boot 4.1.0
Spring Cloud 2025.1.2
Spring Cloud Alibaba 2025.1.0.0
Nacos as the configuration center
After updating a configuration in Nacos, an exception occurs when the application automatically refreshes the corresponding property values in a bean annotated with @ConfigurationProperties.
The same configuration works correctly with the following versions:
Spring Boot 4.1.0
Spring Cloud 2025.1.1
Spring Cloud Alibaba 2025.1.0.0
Therefore, we suspect that this may be a regression or bug introduced in Spring Cloud 2025.1.2.

Can you provide a complete, minimal, verifiable sample that does not use Spring Cloud Alibaba that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.
