I deleted that folder and Substance Painter got successfully launched. Then I deleted same folder for Substance Designer and it launched too. So I guess problem solved? Won't deletion of this file hurt programs? Should I keep deleting these folders each time I install that software now?

Here is a full application error log of SP:

Name of failed Application: Substance Painter.exe, version: 2018.2.1.0, time marker: 0x5b645cf0

I have performed a clean installation of 388.71 Nvidia drivers by clicking the "clean installation" option during installation process, it didn't help, SP still doesn't launch. I did reboot my PC. At least I suppose that's how clean installation is made.
I have also made a second attempt by deleting Nvidia Drivers from the programs list, rebooting and then installing Nvidia Driver 388.71 from scratch. It didn't help either.

I do have Kaspersky Internet Security, but, first of all, long time ago I have added substance painter into its exceptions list, so kaspersky doesn't block it, but just in case I tried to start SP with Kaspersky offline, it didn't help. Other softwares I don't have at all.

Although substance forms say that 388.71 driver (which I had) is the best one to use, I tried to install the latest driver to see if it would help. It didn't help. I also noticed that the same thing happens with my Substance Designer. It doesn't launch either. So it seems all substance products don't want to launch on my PC... (They did before)

I still do not know what to do... help me!

I looked into windows events. Looked into this particular error. It's shown in the applied file. It seems error is associated with Nvidia driver...

I installed 2018.1 version. It didn't launch either...

How do I get previous versions?
Oh, I found it.

Okay, I've added a log file.

Hello, today I was working with substance painter a little, I have imported a number of new textures into substance painter, and after I did so substance painter crushed. I reloaded it, but every time I was opening textures tab in a shelf menu SP was crushing again(textures were sucesscully uploaded). Then after making a number of new attempts SP stopped launching at all. It just shows launch screen for a few seconds and then vanishes into nothing. I assumed it was because of textures, so I deleted them from shelf, it didn't help. I deleted and reinstalled SP from Steam completely several times, it didn't help either. I reinstalled SP from allegorithmic website, didn't help. I deleted SP preferences in the 'regedit' menu, it didn't help. So at this point I think I have completely clean SP on my PC and it doesn't launch at all and I can't make a log file(I uploaded some rubbish here instead, because it demanded it), because it doesn't even launch and it doesn't produce crash report.

I solved this by deleting UV unwrap of mesh in Blender and UV unwrapping it again.

So the problem is I have a mesh that I import into SP from Blender. In blender it contains 3 materials all UV unwrapped across one 2048px image. But when it gets imported into SP it has 6 materials.
Basically if we have material 1 containing faces 1,2,3,4,5,6 in blender, then in SP it gets split into
material 1 with faces 1,2,3 and material 2 with faces 4,5,6. It creates name for second material by using name of material one and putting _NONE suffix at the end.
