no, this is something I never have seen, and deleting the %appdata%\Unigraphics doesn't make any sense for me.
Here Your user settings will be stored.
But as I have seen in an earlier post from Your, You do not have a full SE license but using an academic one.
The next question therefore will be, what is about Your hardware?
Operating system, graphics card, etc.
Those factors are essential to the behaviour Solid Edge will ahve on Your computer.
SE is running on:
Is there more information required?
Yes I think it's obvious: Some malfunction - may be at the time, when Solid Edge stops working - creates erroneous entries to the Settings-folder of SE. Starting Solid Edge with these settings makes it freeze while opening an existent or a new asm-file. After removal of this setting folder, SE starts properly.
I have stored a copy of the settings folder for optional further research for the problem in these files.
You don't say what version of Solid Edge you running. Are you or do you have a mobile device plugged in when Solid Edge stops working?
Oh, I forgot the most important point: it's version 9 academic
And yes .... I have a mobile phone plugged in just for charging
There was an issue in ST9 where plugging a mobile phone into the workstation would cause Solid Edge to lock up. This issue has been fixed in an ST9 maintenance pack.
Depending on which type of academic version you are running you may or may not be eligible for maintenance packs.
Short term solution is to *not* plug your mobile phone in. Longer term would be to download and install the latest MP if you are eligible.
Oh, that's a surprising point.
So the consequence of this lock-up might be leaving the settings-files in an unknown state ...
and YOu also haven't told us, which Maintenance Pack YOu have installed.
For ST9 there is MP10 available, and I strongly can recommend to install MPs when they are available.
