Python system paths initialization on Xbox

[tpaniaki]

Following anxdpanic/plugin.video.youtube#923, I report a failure regarding Python paths initialization on Xbox.

Could you please test
script.module.inputstreamhelper-0.7.0-master-a672b6e.zip

I've still got path issues.

As @MoojMidge pointed out, this seems to affect all addons using python.

Full log.

[MoojMidge]

this seems to affect all addons using python.

Only on some subset of Windows platforms, where presumably access to system file paths are limited due to sandboxing. Possibly related to this change in CPython python/cpython@2438cdf#diff-edff4421a88bdc56335a84a1e5a0ce0eafe5cd0c37dcb1aff03ff075bfb9b57c

It is more of a Kodi issue, but I suggested opening an issue here so that the decision to try to load the LaCrOS browser image could be managed a little better by changing

script.module.inputstreamhelper/lib/inputstreamhelper/widevine/arm.py

Line 13 in 06b88d3

from .arm_lacros import cdm_from_lacros, install_widevine_arm_lacros

to the following:

try:
    from .arm_lacros import cdm_from_lacros, install_widevine_arm_lacros
except (ImportError, OSError):
    cdm_from_lacross = install_widevine_arm_lacros = None

and then changing

script.module.inputstreamhelper/lib/inputstreamhelper/widevine/arm.py

Lines 156 to 157 in 06b88d3

	if cdm_from_lacros():
	return install_widevine_arm_lacros(backup_path)

to the following:

    if cdm_from_lacros and cdm_from_lacros():
        return install_widevine_arm_lacros(backup_path)
