My task was to upgrade Grafana 10.4.2 to the latest version 11.5.2. I am using Windows x64 platform. Like many times before I did all necessary steps, as last step I executed grafana-cli plugins update-all
Then I tried to start the Grafana service, but the web browser could not open Grafana. After running grafana-server.exe manually, I found this at the end of the log file:
logger=server t=2025-03-11T09:28:42.1031709+01:00 level=error msg="Stopped background service" service=*rendering.RenderingService reason="Unrecognized remote plugin message: \nFailed to read any lines from plugin's stdout\nThis usually means\n the plugin was not compiled for this architecture,\n the plugin is missing dynamic-link libraries necessary to run,\n the plugin is not executable by this process due to file permissions, or\n the plugin failed to negotiate the initial go-plugin protocol handshake\n\nAdditional notes about plugin:\n Path: D:\\Monitoring_data\\grafana_labs\\grafana\\data\\plugins\\grafana-image-renderer/plugin_start_windows_amd64.exe\n Mode: -rw-rw-rw-\n PE architecture: amd64 (current architecture: amd64)\n"

Error: ✗ *rendering.RenderingService run error: Unrecognized remote plugin message:
Failed to read any lines from plugin's stdout
This usually means
the plugin was not compiled for this architecture,
the plugin is missing dynamic-link libraries necessary to run,
the plugin is not executable by this process due to file permissions, or
the plugin failed to negotiate the initial go-plugin protocol handshake
Additional notes about plugin:
Path: D:\Monitoring_data\grafana_labs\grafana\data\plugins\grafana-image-renderer/plugin_start_windows_amd64.exe
Mode: -rw-rw-rw-
PE architecture: amd64 (current architecture: amd64)
Then I focused on grafana-image-renderer, tried to remove and reinstall it, the problem remained the same. Then I reverted to the original Grafana version (restored from backup), Grafana started working again (the plugin version is 3.10.1), I tried again to do grafana-cli plugins update-all, the problem reappeared. Does this mean that version 3.12.2 has some problem or did I miss something ?
