I am having issues in the latest QGIS with viewing point clouds in QGIS. Is anyone else seeing this: untwine is generating the ept directory, but only the extent is showing. If I load a previously loaded point cloud or generate my own ept, it still doesn’t display.
I see a possibly related issue:

**Describe the bug**
I am trying to import a laz file into QGIS 3.20.0 but point cloud does not show up at all.
I tried with QGIS in OSGeo4W installer and with Standalone installers (MSI) from OSGeo4W packages. Same result.
I tried with also with QGIS 3.18.3, but I get same result as before.
Apparently QGIS correctly imports the laz file creating the necessary folders and files, but nothing is displayed and no error is reported.

`
Removing and re-importing the file an error pop on:
`Folder $$ is non-empty, but there isn't ept.json present.`
**How to Reproduce**
1. Open QGIS.
2. Import laz file and waiting for initializing.
3. No point cloud show up.
4. Remove layer.
5. Re-import laz file.
6. An critical error from untwine pop on.
You can get an example of file here: https://drive.google.com/file/d/1FWmAP5hG3CtNxQ5DpJ6I9nHbC_SZ5D28/view?usp=sharing (it is a lidar from http://centrodedescargas.cnig.es).

**Additional context**
Digging aroud I find out [this one](https://github.com/OpenDroneMap/ODM/issues/1237#issuecomment-797383604) and it seems this also apply to my case, because lidar scale is around e-07. Following [this one](https://github.com/hobu/untwine/issues/53#issuecomment-785353568) I tried to rescale with pdal lidar scale but got `PDAL: writers.las: Unable to convert scaled value (4160002000) to int32 for dimension 'X'` (same as [here](https://github.com/hobu/untwine/issues/46)). I also try to upgrade pdal from 2.2 to 2.3 as mention [here](https://github.com/hobu/untwine/issues/60?_pjax=%23repo-content-pjax-container) but nothing changes.

I’ve not checked in a while, but I’ll try when I get home to my Windows desktop. The Flatpak of QGIS is still being compiled without PDAL.

Maybe the back-level PDAL that Ubuntu is shipping is causing issues?
I am uncertain if something got fixed in an update, or if I fixed it with the following, but I noted that for QGIS I wasn’t specifically invoking use of 64-bit packages. I changed my /etc/apt/sources.list
entry from:
deb https://qgis.org/ubuntu focal main
to
deb [arch=amd64] https://qgis.org/ubuntu focal main

I use CloudCompare for fiddling with point clouds.
It’s possible to export DSM/DEM to.
