Wappler 6.0 off canvas not working

[famousmag]

Hey @youngjl217,

Similar problem in that thread, check that suggestion:

Wappler 6.0 on Mac going to black screen when saving query

I had something very similar to this, it turned out when I installed it I clicked Allow access to Wappler…what I SHOULD have done is click ALWAYS ALLOW. This solved my issue, not sure if will help you, but may be worth a try.
