Reproduce the reported failure on Neovim 0.12.1, then start in lua/treesitter-context/context.lua around get_parent_langtrees and compare it with the Neovim stack locations shown in the report. Trace the match-percent-separator error during parsing; done means the context plugin no longer triggers this error in the affected scenario.
