Unable to relink to sketchup file

Layout file linked to a skeetchup file. Open Layout file and want to relink sketchup file, since it got a new filename. In relink browser window I can not find the sketchup file. But opening windows file browser - it IS in the folder. Tried to put the Sketchup file in: Dropbox, Google cloud, on PC desktop, in same folder as Layout file - but in relink window from lay-out it is not to be seen anywhere. What might be the problem ?

Tried to unlink in Layout to original file - save - open and choose relink again - same result.

All so tried to choose insert - and finding the new Skp file - but it is not visible.

Can you show the full path to the SketchUp file in File Explorer?

Can you share the new SketchUp file and the LayOut file?

It is not wise to have the file in any cloud location. That’s a great way to end up with corrupted files.
