Mass Effect 1 Feros ExoGeni Bldg Force Field bug??

Here's what helped me. I skipped the cutscene where the force field disappears, so it stayed there.
I loaded the latest save, before the geth ship has fallen. Fought all the geth in the hall again, applied pressure to the hooks and waited till the cutscene will play normally. It is shown in the end how the force field disappears, and if you skip it, it may stay there, resulting in a bug.
