Trouble loading TIFF files

Dear PyImageJ team,

I am currently trying to use PyImageJ on a local linux server with the hope of analysing some z-stack data using TrackMate. I mmanaged to install PyImageJ as per the [instructions](https://pyimagej.readthedocs.io/en/latest/Install.html#installing-via-conda-mamba) via conda/mamba and the installation appears to work via the recommended [test](https://pyimagej.readthedocs.io/en/latest/Install.html#testing-your-installation).

However, when I try to load any TIFF files, for example, using the following Python code:

```
import imagej
ij = imagej.init('/data/axela/Fiji.app')

im = ij.io().open('test_timeseries.tif')
```

I get the following error

```

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "test_imagej.py", line 14, in
dataset = ij.io().open('test_image.tif')
java.io.IOException: java.io.IOException: io.scif.img.ImgIOException: java.io.IOException: io.scif.FormatException: Invalid TIFF file
```

I find that a current workfound is replacing `io().open` with the legacy command `ij.IJ.openImage('test_timeseries.tif'). Then, however, I cannot run TrackMate via the following code:
```
import imagej
ij = imagej.init('/data/axela/Fiji.app', mode='interactive')

im = ij.IJ.openImage('test_image.tif')

plugin = 'TrackMate' # Set plugin for imagej
args = {} # Set the arguments
ij.py.run_plugin(plugin, args, image)
```

Because I will get the following error:

```
Please open an image before running TrackMate.
[java.lang.Enum.toString] Please open an image before running TrackMate.[java.lang.Enum.toStrin
```

Examining this, it appears when I use `IJ.openImage` and check `type(im)`, the variable `im` is defined as a ``. Do you have any advice on how to get around this? Thanks very much for your time!

Best wishes,
Axel.

Reproduce the failure from test_imagej.py at the ij.io().open call, using the local Fiji.app initialization and TIFF example described in the issue. Compare that path with IJ.openImage and the subsequent TrackMate invocation. Done means TIFF loading returns a usable image object and TrackMate can run on it without reporting that no image is open.
