No, one region (France) has a correct way to pronounce crepe. Everyone else should pronounce it the same way, otherwise they’re dumb. If there are language limitations that mean it can’t be perfectly pronounced, they should endeavour to pronounce it as close as possible given the phonemes of their language. In the case of crepe, there’s no reason not to use the “e” sound in “crept”, which would make it the correct, French pronunciation of that vowel.
