Smart Contract infinite loop due to safeApprove SafeERC20

I am attempting to fix code that worked under 0.6.6, but now fails under 0.8.30, and no matter what I do, I can't get past the safeApprove-ERC-SafeERC loop I am in. RemixAI, Grok and ChatGPT all swear by their solutions, but they all loop between these three solution and none of them will compile... how do I get out of this loop? Code snippet of one solution below. Here are the "recommendations" that keep pointing to each other in an endless loop:

Replace:  
'IERC20(token).safeApprove(AAVE, 0);'  
'IERC20(token).safeApprove(AAVE, amount + amount / 1111);'  
With:  
'IERC20 tokenContract = IERC20(token);'  
'tokenContract.safeApprove(AAVE, 0);'  
'tokenContract.safeApprove(AAVE, amount + amount / 1111);'  
Then Replace:  
'tokenContract.safeApprove(AAVE, 0);'  
'tokenContract.safeApprove(AAVE, amount + amount / 1111);'  
With:  
'SafeERC20.safeApprove(IERC20(token), AAVE, 0);'  
'SafeERC20.safeApprove(IERC20(token), AAVE, amount + amount / 1111);'  
Then Replace:  
'SafeERC20.safeApprove(IERC20(token), AAVE, 0);'  
'SafeERC20.safeApprove(IERC20(token), AAVE, amount + amount / 1111);'  
With:  
'IERC20(token).safeApprove(AAVE, 0);'  
'IERC20(token).safeApprove(AAVE, amount + amount / 1111);'  
_sigh_

#### 🔢 Code to reproduce

'''  
\< function go(  
address token,  
uint amount,  
bytes calldata data,  
uint deadline  
) external onlyOwner nonReentrant {  
require(block.timestamp \<= deadline, "deadline passed");  
// Decode the data first to extract r1 and r2  
(address r1, address r2, , , , ) = abi.decode(  
data,  
(address, address, address, address, uint, uint)  
);  
require(routerOk[r1] && routerOk[r2], "bad router");  
address memory assets = new address;  
uint memory amounts = new uint;  
uint memory modes = new uint;  
assets[0] = token;  
amounts[0] = amount;  
modes[0] = 0;  
IERC20 tokenContract = IERC20(token);  
tokenContract.safeApprove(AAVE, 0);  
tokenContract.safeApprove(AAVE, amount + amount / 1111);  
ILendingPool(AAVE).flashLoan(  
address(this), assets, amounts, modes, address(this), data, 0  
);  
}\>

#### 💻 Environment

I am using remix v1.1.3 and whatever other version of remix I can find.
