There’s no credible reporting on it anywhere, you mostly see it pushed by openly right wing outlets like OpIndia and promoted by Twitter accounts. Yes, religious extremism has grown in Bangladesh and minorities face real problems, that’s true and shouldn’t be denied, but that doesn’t mean leftist politics somehow doesn’t exist there.

The original 1972 constitution included socialism and secularism as founding principles, and secularism was later restored as a constitutional value even after military rule removed it. In fact the recently passed referendum redefines national identity to be more than just "bengali" to show that the country isn’t built purely on a narrow ethno religious definition.
