Rawtherapee - Can't open tif from Gimp

After exporting an image in gimp as 32 bit float sRGB (gimp built-in), I can’t open it on Rawtherapee (no error message, RT simply shows a blank canvas)
Darktable can handle it almost normally (in Lightable, zooming in brings an out-of-focus image; in darkroom everything is normal)
Am I doing something wrong?
(As a side note, after uploading the file to the forum, it doesn’t show up)
Gimp output:
https://drive.google.com/file/d/1XoD0IfefQywCyfubxE74kFKQQVjbd2YU/view?usp=sharing
(Another side note, Google Drive can’t show it either)

Gimp 2.10.6
RT 5.4-430 gfbc2872
DT 2.4.4
