QGIS doesn't load up after "Setting up the GUI"

[wandererdmnc]

What is the bug or the crash?

After the flash image loads "Setting up the GUI", it disappears and QGIS doesn't continue to run.

Setting up the GUI

It runs sometimes when I try to open QGIS through

C:\Program Files\QGIS 3.22.6\bin\qgis-ltr-bin.exe; or
C:\Program Files\QGIS 3.16\bin\qgis-ltr-bin.exe

but most often, it does not run. I first encountered this in QGIS 3.16 then I installed 3.22 hoping that it would be resolved. But it still persisted.

When it happened to run, I found the following message log and stack trace. It points to SagaAlgorithmProvider.

These are the message log and stack trace that I copied:

Does anyone know what should be done so QGIS would run normally again?

Steps to reproduce the issue

I just run the desktop shortcut
or go to OSGeo4W Shell, and run C:/%/QGIS 3.22.6/bin/start qgis-ltr-bin.exe

after "Setting up the GUI", the flash image disappears and the QGIS doesn't continue to run. Sometimes it does. But most often it doesn't run.

sometimes i enter C:/%/QGIS 3.22.6/bin/start qgis-ltr-bin.exe --noplugin
(to intentionally get the error for --noplugin) then QGIS runs, with the error log. Then I will be able to copy the same error logs, stack traces. But sometimes QGIS doesn't run.

Versions

please excuse the strikethrough format, i just copy-pasted these from my notepad.

Could you try with a new profile ? (as requested in github issue form...)
https://docs.qgis.org/3.22/en/docs/user_manual/introduction/qgis_configuration.html#working-with-user-profiles

[wandererdmnc]

It still randomly runs even after I created a new profile. I tried to uninstall and reinstall QGIS to no avail. I tried to install in a different partition.

what I observed When it happens to run was that the plugin error was no longer appearing. But QGIS still randomly runs, but it still most often doesn't run. I'm really wondering why this happened...

These are the specs of the laptop that I use which I believe won't cause any issue with QGIS:

Is this still an issue? Have you tried clean installation (e.g. on a VM) and clean profile? Looks like a local issue to me.
