I Can't Sell The Shardeum Coins I Bought On Pancakeswap

I purchased a Shardeum token on Pancakeswap, but I am currently unable to sell it, receiving an error message stating "this transaction cannot be completed due to price movement" when attempting to sell. Consider raising your slippage tolerance. There is a mismatch in the note fee for transferring and rebasing tokens. I would like to receive a refund. I placed my trust in Pancakeswap and made a purchase through their platform. I had to solve this problem by using a crypto DASK telegram channel. The owner of the channel goes by the name K**. Have Pancakeswap been actively working to address this issue? I tried to contact these guys, but they were not available. Perhaps there is someone with sufficient expertise who can assist me. I am looking for advice from a cryptocurrency specialist or a financial advisor who can help me resolve this matter.
