If a firm stops
Most crypto activity in the UK is not regulated. If you invest in crypto, you generally cannot take a complaint to the Financial Ombudsman Service. The Financial Services Compensation Scheme does not protect you if the firm goes out of business, so you are unlikely to get the money back. Being on the register does not create that protection.
A firm offering crypto in the UK must be registered with the FCA, or have permission to promote it. The Financial Services Register shows who is registered and who is operating without permission. If you cannot find the firm, it is unlikely to have that permission. The FCA says avoid the firm. Check which activities a registered firm is allowed to do.
Cover from the compensation scheme is highly unlikely, because crypto is largely unregulated. In 2022 the lender Celsius went bankrupt owing its users $4.7 billion. Many people could not withdraw, and got nothing back. Celsius was a lender, not an exchange. If you leave crypto on an exchange, the exchange is holding it. If the exchange gets into financial trouble, that crypto is at risk.

Two formulations are both kept: crypto activity is not regulated yet, and crypto is largely unregulated. The basics page calls Celsius a lender.
