What utility showed this error? Can you please send a /bugreport?

[mantaionut]

@CaleClink did this crash happened when you switched to high contrast or how can this be reproduced?

[t-clement1]

Having been marked as a duplicate, and as OP hasn't replied, here is my bug report.
I am indeed using high-contrast mode.

PowerToysReport_2024-12-19-14-31-40.zip

[mantaionut]

@t-clement1 is this crash 100% for you when you are in high contrast or does this crash happen when you switch to it?

[t-clement1]

It happens at random intervals when in HC mode, and happens with almost 100% probability when switching to HC mode, or when switching between different HC mode colour presets.

[t-clement1]

Still throwing errors every day when booting, or changing themes related settings. PowerToys Run is literally unusable as is.

[justFleyd]

i use win11 darkmode and the setting dark in "PT Run" then sometimes also use the high contrast mode on top for a darker event viewer and old settings and happens in the second when i switch to High Contrast mode (shift+Windows+print)

it spits exactly the same Error 2 times (2 windows) in the moment of switching

[mantaionut]

@justFleyd are you using a custom high-contrast theme or one of the defaults?

[Christopher-James-Francis-Rodgers]

"Power Toys Run ran into an issue" - "Something went wrong".

This error occurs every time I switch to, or switch from my custom Windows 10 'High contrast' theme.

This error does 'Not' occur with any of the four 'default' (out of the box) Windows 10 'High contrast' themes.

See attached:

*.theme file (.txt extension added),

*.deskthemepack file (converted to *.zip),

*.png image file,

error message *.txt file,

and error log *.txt file.
