Jdtls gets stuck on windows 11 in powershell

[mKrswe]

Hi everyone,
I have to use Windows and the Powershell as we are not able to use WSL in my company. The nvim-java setup works quite well but I have some difficulties with the jdtls getting "stuck". What I mean by that is that when I am making code changes which have some invalid syntax in the meantime, the jdtls gets stuck and I get no auto suggestions and so on. An example is writing an if-clause which is only valid after implementing the condition and content of the if-clause.
I "fixed" the scenario with a autocommand which reattaches jdtls every time I save the buffer.
Do you have any other ideas or solutions for this problem?
