[Qgis-user] ISSUE QGIS keeps freezing - QGIS Desktop 3.10.4

[Koos Fransen]

Hi Bo

Thanks for your quick response!
Sorry for the minimal information provided, I wasn't sure what to add (first question to the QGIS user list).

To answer your questions:
OS: Windows 10 - 64 bit
QGIS version: 3.10.4 64 bit, stand-alone installation

I'm not in any networked set-up, I'm working from home on my own computer. I have only one plugin installed (QuickOSM), and I've already tried uninstalling, but without any difference.
Since my question I've been trying some things, and I have deleted the temporary QGIS files in my Local/Temp folder. When I open and use QGIS now, I have the feeling it's more stable again. It gives a hint of freezing up at the start, but afterwards all goes quite well again. Then again, not sure of this is a solid solution for fixing this issue, as I have experienced this issue before completely deleting and reinstalling everything QGIS-related on my laptop (using REVO uninstaller). After this, QGIS worked fine for about a week until today.
I do recall trying to load some large files into QGIS, maybe they were stored in a temporary directory somewhere and deleting the temporary files helped?

Anyways, it might be relevant for me to know. I've switched our courses from ArcGIS to QGIS, and I'm really happy about it, but I would like to be able to help my students if these kind of problems occur.

Thank for the help already, not sure if there's more to do for now, but let me know if you have any more ideas.

Kind regards
Koos

Hi Koos:

That's not much information to go on.

What about: OS type and version ?  32/64 bit os ?  QGIS version ? QGIS 32/64 bit ? network environment ? Normal stand-alone installation or Network installation ?

I'll hazard a guess based on my own painful experiences: You are working  in a networked windows setup, where your IT department has made some modifications for home directory (including temp file placement) and/or the userdata environment - maybe making it fully dependant on the network. And maybe You are using the same login account for all pupils. Combine this with a marginally functioning network and it will be a train wreck

Another  scenario: You have installed some plugin, that's not working correctly.

What you can test:

  *   Disable/Remove all plugins from QGIS and test if the problem goes away
  *   Load some GIS data locally on you computer and disconnect the computer from the network. Then test QGIS again.

That said, QGIS ver. 3.10 onwards has long startup times. However it's quick and stable after that

Dear all

I have a question regarding QGIS.
I'm using QGIS for my classes, but since a recent install my QGIS keeps freezing right after startup. It doesn't respond until after a minute, then I can open some files and then it freezes again. This keeps on going, making it impossible to keep working with QGIS.
I've tried reinstalling, which always helps at first, but after a couple of days it starts freezing again. I've also tried with different versions, with the same result.

It might maybe have something to do with temporary files?
Has someone experienced the same issue, and are there possible solutions that you know of?

Thanks!
Koos
