Did hitler blame jews for Reichstag Fire?

Yes

Explanation:

In February 1933, Bulgarians Georgi Dimitrov, Vasil Tanev, and Blagoy Popov were arrested, and they played pivotal roles during the Leipzig Trial, also known as the "Reichstag Fire Trial". They were known to the Prussian police as senior Comintern operatives, but the police had no idea how senior they were. Dimitrov was the head of all Comintern operations in Western Europe. The responsibility for the Reichstag fire remains a topic of debate and research.[3][4] The Nazis accused the Comintern of the act. However, some historians believe, based on archive evidence, that the arson had been planned and ordered by the Nazis as a false flag operation.[5][6] The building remained in its damaged state until it was partially repaired from 1961 to 1964 and completely restored from 1995 to 1999. In 2008, Germany posthumously pardoned Van der Lubbe under a law introduced in 1998 to lift unjust verdicts dating from the Nazi era.
