These decisions come less than a year after a £6.6m budget cut was reimposed despite being reversed earlier in 2023.
At the time the Scottish government promised the funding would be provided as part of the 2024/25 budget.
Mr Gamble said the Creative Scotland funding issue was “truly shocking ” given the repeated warnings from the arts sector over the last two years and the Scottish government’s promises in response.
He said: “Creative Scotland cannot invest funds it does not have. If the government continues to withhold information and resources, cultural organisations will shortly lose the vital support that, astonishingly, all individual artists have now lost.
“These are devastating impacts that are clearly at odds with the government’s stated direction of travel. Ultimately, every citizen will feel the effects.
“Art and culture are not luxuries – they are an essential part of a healthy, thriving society. We urge the Scottish government to deliver on their commitments and increase support before any more damage is done.”
A Scottish government spokesperson added: “We have increased arts culture funding this year, as the first step to achieving our commitment to invest at least £100m more annually in culture and the arts by 2028/29.
“The Scottish budget continues to face significant challenges. We are considering the implications of the actions announced by the Chancellor on 29 July for our public finances, and the next steps required by the Scottish government.”
