I've tried multiple files and also Lightroom or Photoshop are doing fine, but whenever I try to merge photos via Bridge (v.10.1.1 AND v.11.1) the preview is nearly all grey. Merging and saving the pano works fine, but it's really annoying not to know what the result's going to be.
I'm running Windows 10 Pro and my AMD Radeon RX 5700 driversversion is the RadeonProEnterprise.
Sorry to hear about this issue with Bridge. Could you please try resetting the preferences of Bridge and let us know if it helps? https://helpx.adobe.com/bridge/kb/troubleshoot-errors-freezes-bridge.html
