PrusaSlicer fails to bridge small gap
Hi, I have a small gap in my print which should be easy to bridge. However, PrusaSlicer does not detect that and tries to print in mid-air.
Is there any way to tell PrusaSlicer to properly bridge the gap?

Who knows without the model or the settings you are using. Too little information. Please save your project as it is in the failing state from Prusa Slicer using File>Save project As. Then take the resulting .3mf file and ZIP it up. Then attach the zip here using the attach file button. It must be zipped or the forum wont accept it as it only allows a VERY limited selection of file types.
A project file is a snapshot of your setup. It contains the model plus all the settings, any modifiers etc too. It allows us to slice exactly as you are doing and look at the preview and settings. The model can also be checked too if needed.
Also what version are you using ? One of the release versions or an alpha ? All required information to diagnose issues.

Sorry for not providing enough information.
PrusaSlicer version 2.5.2+linux-x64-GTK3. File: Top2.3mf. The problem is at the layer height 2.40 and again at the top at height 17.60.
I figured out that the problem is related to the minimal perimeters, which was set to 4. Apparently, these take priority over forming a viable bridge. When I reduce the number of perimeters (for this one layer) to 1, it's ok. So that solves it for me, unless there's a better option.
RE: PrusaSlicer fails to bridge small gap
Yeah its now trying to fit your 4 perimeters in there as it can now. A couple of things about your settings though. For this geometry you would normally have to add supports in for those unsupported perimeters. Personally I would also turn off thick bridges as that makes their layer height the same as the extrusion width so twice as thick in this instance. You might want to turn on detect bridging perimeters too as that gives a better visual indication of where support is needed after slicing.
With this particular object though if you want to bridge with the 1 perimeter then you can use a couple of height range modifiers so the rest of your perimeters are unaffected. I've attached an example for you.
