PowerToys Run

Steps to reproduce

Hi I'm having trouble calculating something or finding something by using powertoys run many times.
Usually some error messages come up and once a day the error messages infinitely generate as a photo attached. I had to shut down powertoysrun in task manager almost every single day. I would appreciate it if you fix it at your earliest convenience.

following is the error message when it occurs.

This is #17371 and #9143 . So I'm guessing we're still getting this from time to time.
I wonder if it's got something to do with character set. Looking at recent occurrences, this one is using Korean characters while #17371 is using Chinese characters if I got that correctly.

Can you please test something to see if we can find out which module might be causing this?

In settings, disable every PowerToys Run plugin and restart the computer.
After the computer restarts, enable the PowerToys Run plugins one by one while testing the query that is causing these errors, to see if we can identify which one is causing this behavior for you. /needinfo

It seems that windows Search is the problem. As you said, I turned off all of plugins and rebooted computer and I turn on calculator and typed the numbers several times and there's no problem but upon turning on Windows Search, error message just come up. when I re-run several times, the error message window that has no content iterated infinitely.

@franky920920 , sorry to bother you, but is this something you were ever able to repro when using Chinese localization?

Can confirm have the same issue here in zh-CN using PowerToys Run with most plugins turned on (including Windows Search). Will try to reproduce later. Log attached, with most plugins turned on. Since it's totally random, sometimes it works fine and sometimes it'll crash, I'll turn Windows Search off to see what's coming next.

Sorry, missed this mention. Let me check this later.

Thanks for the feedback! What about the test build? Did you try it?

Happy to test but was not aware there was a test build, please point me in the right direction and I'll give it a whirl. 🙂

Check out this comment: #18166 (comment)

And don't forget to delete PT Run image cache by deleting following file <AppDataDir>\Local\Microsoft\PowerToys\PowerToys Run\Settings\ImageCache.json before testing.

@JoClever Would you be willing to install test build as explained here #18166 (comment) ? Thanks

I am happy to report that I cannot reproduce the crashes with the test build, even with thumbnail generation enabled!

[stefansjfw]

@JoClever Thanks for the testing and the feedback! And do you experience some performance issues with PT Run? Are thumbnails loaded for different apps?

[stefansjfw]

Fix for this issue is merged and will be included in the next PowerToys release. Big thanks to everyone that helped locate the cause and for the testing.

For those who tested the debug build - remember to uninstall it and install an official release of PowerToys again to be able to receive update notifications once the new version is released.

After using the debug build for a while, I can't find any performance issues. Icons are also generated reliably as far as I could tell.
Looking forward to the next release!

Coming from #24974 with comment to update here.

I had the "Dispatcher processing has been suspended" error using PT Runs since updating to 0.68.1 from a rather old version. The issue was happening on about once every 2-3 use.

Disabling thumbnail generation fixed the issue, no error in the last 2 work days.
