Not able to create the provider instance after upgrading the package

“fuels”: “^0.84.0”

fuels@0.82.0 is the last version compatible with the beta-5 network. If you want to use a later version, you should run a local node.

Any idea when the next version will be compatible for the beta-5 network with the new changes in the package

There will be no more versions compatible with beta-5. There will be another version of the network at some point that will work with newer fuels versions, but there is no date for that currently.
