As mentioned by @chalut01, version 3.6.1 contains an important security fix, so you'll need to setup renderer_token, as mentioned in the linked article. On top of that, image-renderer version 3.6.1 should be run with the following versions of Grafana:

• 9.1.2 or later
• 9.0.8 or a later patch release
• 8.5.11 or a later patch release
• 8.4.11 or a later patch release
• 8.3.11 or a later patch release
