You can try for previous version:
https://account5.wappler.io/download/beta/Wappler-Mac-7.0.0-beta.26.dmg (Intel Chip)
https://account5.wappler.io/download/beta/Wappler-Mac-arm64-7.0.0-beta.26.dmg (Apple Silicon)
Or change 26 to the one you had and works as expected..
PS: Remember this is a Beta version and maybe you should rely on the stable version until beta ends to avoid things like this..
