Animations Not Working Properly on Import from Blender to Unity

Unity Engine

I have a set of animations on my armature in blender which are all working fine. It’s four different animation actions which I exported using the correct settings for exporting an animated model. See below export settings from blender:

When I drag the model into the assets folder in my Unity project, the animations look all wrong. They have 1 or 2 frames and move weirdly, not like they should. I get the following error in Unity upon importing:

Which does not make sense as in blender, the frame rate is set to 30 FPS.

When I select the FBX in the asset folder and click into the animation tab, as you can see the frames are not getting picked up by Unity:

I tried changing the animation type to Legacy, I saw this was a solution online but it did not affect anything:

I am really confused and would greatly appreciate any help on offer, thank you!

Unity version 2022.3.10f1
Blender version 3.3.1

I found out that the version of blender I was using had a bug. After installing the latest version, Blender 4.0, re-exporting my animations, then importing them into Unity, they now work as expected.
