SysID crashes due to imgui assertion failure

[sickingp]

SysID had been working fine on my Windows 10 laptop but isn’t any more. Now when I start sysid I get an assertion error Expression: blocking_modal != 0 at D:\a\thirdparty-imgui\thirdparty-imgui\imgui\imgui.cpp Line:6298. Maybe it’s a red herring but I don’t have a d: drive mounted on my laptop.

I think this problem was caused by a sysid crash I had for another reason (my characterization program was sending poorly formatted telemetry data to sysid). Every since that crash, sysid won’t start because of the imgui error. I assume imgui is in some strange state relative to window management as a result of the original sysid crash.

I’ve re-booted and re-installed sysid but the imgui problem persists.

Any ideas?

You can work around this issue by removing C:\Users\username\AppData\Roaming\sysid*.json. The 2022.3.1 release also has a number of sysid fixes, so upgrading may fix the issue too.

Nice. That worked. Thanks for the quick response!
