Using latest on Win10-64, I try to HDR-merge 3 TIFF files, and the program crashes (closes abruptly with no message) early during the merge process, if auto-align is enabled.

The TIFF files were exported by Capture One 20, originally from Olympus E-M1II RAW files. 

Oddly, merging those original Olympus RAW files directly in Affinity Photo succeeds, but unfortunately chromatic aberrations are not corrected so it's not a valid option.

I attached crash report files.

Thanks. It isn't crashing for me with those images. Can you try changing your Renderer to WARP in Preferences > Performance and try the HDR merge again?

If your graphics drivers are causing the crash, chances are they need updating. 

Changing to WARP renderer prevented the crash and I was able to complete the merge successfully.

FYI, I am using the latest WHQL (stable) Nvidia drivers, and tried both my old GFX 670 and new RTX 2070 Super cards. In both cases, the default renderer crashed.
