I am currently using the shield generator to generate a shield for the AUNIS stargate mod, and the vortex ("Kawoosh") is able to destroy the shield blocks, defeating the purpose of the shield. Would there be a way to make the shield regenerate without turning it off and back on?

What version?

Also if the stargate mod forcibly destroys those blocks then it's buggy. The shield blocks are marked as non destroyable and other mods should respect that. Report to them. Shield blocks are given the same hardness as bedrock. Other mods should not destroy them under any circumstances

1.12-7.73 is the version of the mod. It is a buggy mod, the developer is struggling with the programming to attain their goal of canonity. I will send the AUNIS dev a bug report as well.

What do you mean by 'it is a buggy mod'? What mod is buggy?

AUNIS is buggy. There are many problems with the mod, be it issues with server lag or equipping an item causing an unavoidable crash.

Ah ok
