UPDATE:
Some new options are now available to the FS Developer using native Sketchup SKP file versions that are newer than ones installed version.
Whereas Sketchup SKP file versions changed with nearly each numeric version since at least 5.x, versioning reportedly stops with 2021.
Thus, Sketchup SKP file versions 2022, 2023, and 2024 are now reportedly interchangeable, and can be directly Opened in any of those (3) installations.
Many of us prefer to work with the free desktop Sketchup Make which reads / writes 2017 SKP file versions.
If we wish to Open a Sketchup SKP file version that is older, we can easily do so, with a caution that if we Save into that file, it is updated non-reversibly to the numeric version which we have installed and are using to Open the file.
But if we wish to Open a Sketchup SKP file version that is newer, we can not easily do so.
And if we wish to Save a Sketchup SKP file version that is older, we also can not as easily do so.
To work around this, we can install either- or all of- the following plugin Ruby scripts to inter-convert SKP files for most of the Sketchup versions FS Developers may install / use, as well as the now more limited mix of numeric SKP file formats available for download via 3D Warehouse:
Eneroth3 / Open Newer Version
SketchUp plugin for converting and opening models made in a newer version of SketchUp.
For more info about the C++ programs used in this extension, see cpp/README.md.
Requirements: SketchUp 2014+ / Windows 64 bit
Supports SketchUp models from versions up to 2019. For each new major SketchUp version the C++ program in this extension needs to be updated to use the new SDK, supporting that version.
IIUC, as of 2022, author Christina Eneroth reportedly has updated this plugin to work compatibly with Sketchup versions through 2022 - 2024:

I’ve finally had the time to update the extension! Now 2022 and (hopefully) all other versions released in a near future should be supported.
Sorry for the delay.
NOTE: This plugin may still be under revision, and the associated Extension Warehouse page offers this disclaimer:
"Please note, due to some technical issues in this plugin I recommend using Eneroth Legacy Save instead."

Eneroth3 / Legacy Save
This extension quickly saves the model in a legacy SketchUp version. In contrast to utilizing the native Save As... command you don't need to accept the file location and confirm overwrite on each save.
If you have colleges stuck in older versions or want your files to be accessible using SketchUp Make, which stopped being developed after version 2017, you may find this extension useful.
If the file is already saved, this command will function similarly to the native Save command, and save the file to the same location as the same SketchUp. If the file has already been saved to a newer version than you want to save as, first use native Save As and select what version you want to use.
Activated from File > Save in Legacy Format.
