Do I understand the description correctly that the Spring Tools work nicely for a while, and then suddenly the error appears?

I think we need to details here in order to find out what is going on there. If you open the Output view in VSCode, there should be an entry called vscode-spring-boot-debug-log in the dropdown. Does that entry exist and what does it contain?

Also, is there a way to reproduce this? Specific steps that lead to the error? And does it happen independent of the project that you have open, so the error appears for other Java/Spring Boot projects open in VSCode as well?

@BoykoAlex might also have additional ideas which information could be helpful here in order to debug the issue.

I can only re-emphasize that we'd need the spring boot language server log to proceed. Feels like an exception has been thrown while creating response for initialize message or exchange of capabilities between client and server...
I'd find Boot Language server log file setting under Spring Tools settings:

To output Spring Boot Language server log to a file and then try things again and attach the log file here.

Any additional information from your side @conquhare ?
