Could not deserialize ATN with UUID 59627784-3be5-417a-b9eb-8131a7286089 (expected aadb8d7e-aeef-4415-ad2b-8204d6cf042e or a legacy UUID).

Hi in my project I need to use Antlr-4.9.3 version, along with I am using Antlr-Runtime 4.5 version. So sometimes I am receiving Could not deserialize ATN with UUID 59627784-3be5-417a-b9eb-8131a7286089 (expected aadb8d7e-aeef-4415-ad2b-8204d6cf042e or a legacy UUID). error and sometimes works fine. What could be issue?

You need to match the runtime version with the tool version

Is there any reason for why it works sometime? Will it be because of legacy UUID?

I could not tell you without looking at your grammar etc - but I am surprised that it works at all. As per the documentation, you MUST match the runtime you use with the version of the tool that you use to generate the code.
