Bug #88618	Crash on running queries

Description:
On running any query (clicking on execute query, clicking on Select rows on table), system crashes, showing MySQL Workbench Unexpected Error window with Parameter is not valid error.
Windows tabs on top change to white background with red stripe around it.

I have uninstalled everything Workbench related, deleted folders in ProgramFiles and AppData, installed from freshly downloaded Workbench Installer. Didnt try previous versions, had same problem with 6.3.9 version.

Seems like some background picture is missing? Access problems?

Logs shows this:

How to repeat:
Run query

Thank you for the bug report. I couldn't repeat on similar environment, try uninstalling it and delete the folder: C:\Users\your_user_name\AppData\Roaming\MySQL\Workbench then install again. Thanks.

As already written in OP, I have uninstalled and deleted all the folders, but that didnt help. The same error was already present in 6.3.9 version.

Anything else I can check or try to debug?

Thank you for the feedback. Please print the output of the below statement using the mysql.exe command client:

mysql 5.6 > show variables like '%versio%';

and attach the screenshot (using Files tab) of the steps you reported. Thanks.

Since I'm using workbench to connect to other mysql servers, I dont have mysql server installed on my pc.

Also, version of mysql server doesnt play a role in this bug, since workbench crashes on different servers with different versions.

This is the result of one of the servers I'm connecting to:
innodb_version	5.6.33
protocol_version	10
slave_type_conversions	
version	5.6.33-0ubuntu0.14.04.1-log
version_comment	(Ubuntu)
version_compile_machine	x86_64
version_compile_os	debian-linux-gnu

Thank you for the feedback. With your generic description of 'running queries crashed' I couldn't repeat connecting with a remote or local server we don't also similar bugs reported against 6.3.10 version, so I assume is something restricted to your environment. Please provide a repeatable test case with create table, insert data statements and queries which provoke the crash (use Files tab to attach the SQL script). Thanks in advance.

Screen capture of bug happening

I have added the screen capture to the bug, since its the same with new version of workbench.

Again, I realize its not workbenches bug, its something on my side, but its really really annoying and I cant figure it out.

I have also tried to reinstall EVERYTHING mysql related on my PC, also running mysql workbench with administrator rights.

Please try version 8.0.13. Thanks.
