Hi Winstone. God’s blessing with you also.You should ask protestants yourself! The difference is that protestant believers will say that they accept the ‘authority’ of the Bible as the all sufficient revelation of what is necessary for salvation and going to Christ directly without the intervention of a priest is unnecessary. Of course that may sound an over-simplification but there are marked differences in Catholic and Protestant theology
It should not need to be explained but surely the answer lies in the difference between Catholic and Protestant theology. The priest is a stumbling block to gaining direct access to Christ so they rely and protested historically on the ‘authority’ of the Bible itself. So, they appeal to the mercy and forgiveness of God from Holy Scripture, and they can make a good case for it. In other words, the Bible gives its own assurance. Here are some examples, which should also be consoling to Catholics!
God Bless You

Just narrowing the “protestant” brush stroke, here.
This, from the Apology of the Augsburg Confession.
Jon2] For we also retain confession, especially on account of the absolution, as being the word of God which, by divine authority, the power of the keys pronounces upon individuals. 3] Therefore it would be wicked to remove private absolution from the Church. 4] Neither do they understand what the remission of sins or the power of the keys is, if there are any who despise private absolution. 5] But in reference to the enumeration of offenses in confession, we have said above that we hold that it is not 6] necessary by divine right. For the objection, made by some, that a judge ought to investigate a case before he pronounces upon it, pertains in no way to this subject; because the ministry of absolution is favor or grace, it is not a legal process, or law. [For God is the Judge, who has committed to the apostles, not the office of judges, but the administration of grace, namely, to acquit those who desire, etc.] Therefore ministers in the Church have the command to remit sin; they have not the command to investigate secret 8] sins. And indeed, they absolve from those that we do not remember; for which reason absolution, which is the voice of the Gospel remitting sins and consoling consciences, does not require judicial examination.
