Cannot export blender files, please help

So I was using s4s for exporting poses for blender normally for a long time, then suddenly during exporting one set of poses last week it bugged and started exporting poses without action rig so it couldn't be appended to a sim rig in blender, I checked the paths and nothing online offerred a solution. I tried redownloading and reinstalling but it persisted, then I tried recovering PC to a certain time in the past and that created some other problems like all my downloads deleted and DAE files. However when I want to export poses instead of empty action file I get this error message instead. I've tried everything and have no idea what could have happened to cause all of this in the first place. My antivirus is turned off to my knowledge and the path seems to be fine. Anyhow this is the error message:
