RPI - Unable to play videos - error: InputStream Adaptive: Unable to load widevine shared library

Bug report

Your Environment

• Netflix add-on version: 1.12.4
• Operating system version/name: LibreELEC (official): 9.2.6
• Device model: Raspberry Pi 4B

Used Operating system:

• Android
• iOS
• Linux
• OSX
• Raspberry-Pi
• Windows

Describe the bug

Program will not play when selected in the menu, no error and remains on the menu rather than the play window

Expected behavior

hitting enter on a netflix program should stream the video, or at least show an error that it could not play

Actual behavior

Silent, no error and remained on menu page. Have played around with the resolution settings and everything else the wiki suggest for video issues. On kodi disabled hardware decoding and set a 720p resolution, still no help

Steps to reproduce the behavior

1. Install LibreElec onto SD card from official raspberry pi site
2. Insert into Pi
3. download CastagnalT repo zip onto usb stick
4. On Kodi Install plugin-from zip
5. Goto Repo and install dependencies
6. Start plug-in
7. log-in to account
8. Follow prompts for installing widevine via chrome
9. find any program and hit enter

Possible fix

Total noob here but probably something to do with the log line 799 GetDirectory - Error getting /usr/lib/kodi/addons/inputstream.adaptive/ or the chrome installer for widevine could be silently failing?

Debug log

ARMv7 4.10.1679.0 here if anybody needs

https://k.slyguy.xyz/.decryptmodules/widevine/4.10.1679.0-linux-armv7.so (just rename it to libwidevinecdm.so) or http://archive.raspberrypi.org/debian/pool/main/w/widevine/widevine_4.10.1679.0.orig.tar.xz (extract and find the file in widevine\opt\WidevineCdm_platform_specific\linux_arm"

Here’s what worked for me (I think this is doing the same as @ancebfer above but easier for those less experienced with the command line):

Go to Add-ons > My add-ons > Program add-ons > InputStream Helper > Configure > Restore Widevine CDM Library

Select the most recent previous version. The one that worked for me was …77.0
