Minimal reproduction steps

1. Deploy token contract with openTrading function

function openTrading(address _router) external onlyOwner {
		require(!tradingOpen, "trading is already open");
		uniswapV2Router = IUniswapV2Router02(_router);
		_approve(address(this), address(uniswapV2Router), _tTotal);
		uniswapV2Pair = IUniswapV2Factory(uniswapV2Router.factory()).createPair(
				address(this),
				uniswapV2Router.WETH()
			);
		uniswapV2Router.addLiquidityETH{value: address(this).balance}(
			address(this),
			balanceOf(address(this)),
			0,
			0,
			owner(),
			block.timestamp
		);
		IERC20(uniswapV2Pair).approve(address(uniswapV2Router), type(uint).max);
		swapEnabled = true;
		tradingOpen = true;
		firstBlock = block.number;
	}

2. Run the open trading function on the ignition hardhat

Hi @billalxcode thanks for reporting this!

I tried to repro by writing an isolated test in this project, but I couldn't repro the panic: https://github.com/agostbiro/undefined-call-instruction-location

If your project is public where the panic happens, could you share that please? Or alternatively could you have a look at my repro project and let me know what to change to reproduce the panic?
