I really don't know much at all about Crickets and you're right that there are quite a few similar European species but I think it might be Eupholidoptera schmidti AKA Schmidt's Marbled Bush-Cricket - see for example https://www.inaturalist.org/taxa/509455-Eupholidoptera-schmidti
Not the best picture from my phone but I assume this is some sort of spider nest or something
