Stack Trace

See compiler output above

Minimal Reproductible Example (MRE)

From Arduino library AsyncEspFsWebserver v2.0.2 (latest) by Tolentino Cotesta, compile example customOptions, without any modifications

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).
