PancakeSwap WCUP2026 Token Cannot Be Swapped Back to BNB

I have been experiencing a persistent problem on PancakeSwap for the last two days while trying to swap the token WCUP2026 back to BNB. Every time I attempt this swap, I receive an “increase slippage” error, even though I have already tried adjusting the slippage to many different levels and changing the amount and time of day. No matter what amount I try to swap, what time I try it, or which slippage percentage I set, the transaction does not go through and the same error keeps appearing. I contacted support and was only advised to increase the slippage, but this suggestion did not solve the issue in any way. I expect this problem to be investigated in detail and technically resolved so that I can successfully swap my WCUP2026 tokens back to BNB without errors. I kindly request a clear explanation of the cause of this issue and a concrete solution that allows me to complete the swap.
