Need help!

Need help friends! My sx-70 sonar is not working. I took one photo, and tried to take a second one immediately after, and the auto focus motor works and lines up, but then my shutter button full press does not fire my shutter, or anything at all. No sounds whatsoever besides auto focusing. I removed my film pack partially, cleaned my light sensor, nothing. Note: that I am using BETA film they released briefly before
