I was working on an important project for my interior firm however due to powercut my PC shutdown and after restarting the last saved Skp file isn’t opening.
I need urgent support on this.
This is an user forum, not official SketchUp support. If you want others to try opening your file, you must share it.
There is no free version of SketchUp 2023. Are you using a cracked version?
Trail 2024 version
Why did you put “Free Plan” 2023 in your forum profile?
The file you shared says it was made with a cracked version of SketchUp 2023. It’s missing large chunks of data and cannot be recovered.
Unfortunately this seems to be a common source of file corruption.
