@WhyEvenTry?, I had similar problems not so long ago when I updated to version 4.x.x, and I had wallets that were created with versions 3.x.x - although I must mention that it was the version for Android. At that time, I solved that problem by going back to the old version and emptying the old wallets.
Can you write which version of Electrum you use, is it a desktop or mobile version and do you have your seed stored safely?
It would be better if you move your topic to ->

I have tried transferring the entire amount in my wallet and have tried transferring much less than the total amount in the wallet. Every time I get the same error. One thing I noticed is that the wallet details say it is "watch only." I created a new wallet and the wallet details info is much newer. Might be because I've had the original wallet for a long time?
I have screenshots but, don't have the time to upload them to a hosting site and attach here. The error code reads: Transaction created. Present this QR code to the signing device." Below that it says, "Warning: some data (prev txs / "full utxos") was left out of the QR cod as it would not fit. This might cause issues if signing offline. As a workaround, try exporting the tx as a file or text instead."
It seems that might be my issue is that somehow the wallet became watch only. Or, am I wrong? Quick search pulled up some complicated directions for sweeping the key??? Crunched for time or I would have done more digging.
