After installing the release Cakewalk_by_BandLab_Update_Setup_27.09.0.120(Rebuild_2) and opening or creating a file, the transport plays for about 100ms and stops and returns to the starting position. No error message, no dropout message. Same behavior for any file, any audio or midi. new or existing. I can not revert to the previous version as the error says the build is not present. Please help
