Keyboard stucked on one key

When i connect to my windows pc and start texstudio, the first key i press is stucked and after pressing different keys, only this letter appears again and again. So as an example: Typing „hello“ will give me basically „hhhhh“. The problem does not appear, when using different programs, such as notepad or editor. Anyone who has similar issue? Or any idea how to fix it? JFYI: i am using an ipad pro 2021 and connecting to windows pc with windows 10. Any help is appreciated Bests MC
