Screenshots

Flow Launcher Version

2.0.0

Windows Build Number

26100.6584

Error Log

[cethink]

It's the same when inputting 'f'. Let me check again.

[cethink]

It seems that entering any random character will cause a freeze for a while. I have already cleared the logs, and no logs were generated during the freeze.

Can you check if this can help?

I tried it out. The first time I input something, it freezes for a moment. If I input again within a short time, it doesn't freeze. But if I input again after a while, it freezes again.

In addition, when clearing the cache, if it has already been cleared, trying to clear it again will result in an error:

It seems that PR cannot resolve your issue.

In addition, when clearing the cache, if it has already been cleared, trying to clear it again will result in an error:

Will fix it in another PR.

Could you attach a demo video?

[cethink]

Bad luck, I'll record it later to take a look :(

The same situation as above has happened again.

I removed this option, let's take another look.

The problem remains, and

The problem remains, and

Check your network please

[cethink]

I checked for updates about ten minutes ago, and it succeeded immediately.

I turned on the system proxy and this address also went through the proxy. I'll turn off the proxy and check again.

[cethink]

Still...

[Jack251970]

@cethink Could you please use this version, enable Debug log level and then test it again? And please upload your log file. Thanks!

[cethink]

Ok

[cethink]

It just got stuck twice in a row. The first time lasted about one minute, and the second time lasted about ten minutes.

重装一下试一试呢？换一个盘装，我感觉可能是ssd读写的问题
