交易失败 - 钱包到钱包和钱包到合约余额

Question

I've just started with Solidity and, in order to understand and learn Solidity and the combination with Remix, I've copied some contracts. At the moment I'm testing the contract "Token69", if I try do deploy the token now, I get the error message:

"creation of Token69 errored: Error encoding arguments: Error: invalid BigNumber string (argument="value", value="", code=INVALID_ARGUMENT, version=bignumber/5.1.1)"

I found out that the reason for my problem is because of the data laying in the constructor. Can I delete these parts of the code without any problems or do I have to fulfill those with data? In addition to that, if I take out the Constructor and try to deploy the token (everything on standard gas limit and fee all other standard value of Remix) the token is permanently on "pending Token creation" There is no error or bug report or anything. I don't really know what to do.

Can anyone help me, please?

---

I've tested another contract and now I can deploy the contract and token are sent to my wallet but I can't transfer the token to another wallet. I can't find the problem in this contract, can anybody help me with this?
