Can't install 3DN BIP!!! Blender crash when try to install! Linux OS about 3dn-bip HOT 6 OPEN

Well, if it does any help... I tried to comment the 35th line in formats.py, which contains:

PIL_FORMATS = {
'PNG': _PILFormat(magic=b'\x89\x50\x4e\x47', tests=_png_tests),
# 'JPG': _PILFormat(magic=b'\xff\xd8', tests=_jpg_tests),
}

Then it passed the tests and get installed with no crashes. PNG previews working as intended with no issues, but obviously it does not solves anything, simply a hint toward the solution.

Update:
It seems that there is no issues to preview JPG files either. I did some tests in the older python 3.8 environment and jpg test passed, but _run_test function crashes within Blender's versions which is 3.10 and presumably 3.9, so my initial thoughts that this might be in a range of this particular function and the way it being tested by.

@FidoAnh @tingjoybits Here is what Anthony Aragues says:

following up on pip issues, has to do with version of python
/snap/blender/current/3.1/python/bin/python3.10 -m pip install --upgrade pip
/snap/blender/current/3.1/python/bin/python3.10 -m pip install Pillow==8.4.0 --user
appears to be the fix

Does this information help?
Would love to merge a PR, if someone is willing to contribute

Upgrading Pillow to the latest version (currently 9.2.0) also seems to fix the issue (although thorough further testing is needed).

BTW, your first line in the fix should read something like:

/path/to/blenders/python/python3.10 -m ensurepip --upgrade --user

OK, unfortunately I've mixed up the Pillow versions. So only the downgrade works...

Interestingly the problem does not occur running the test formats functions, with blender's python but outside of blender.

@bonjorno7 do you think we can integrate this fix/workaround in the BIP code directly?
