Issue with Caps Lock key causing a processing delay on 2018 MacBook Pro

I began to notice recently that whenever the Caps Lock key is pressed, there's a processing delay that I can tell is happening because I see the spinning wheel appear briefly and I am unable to type (or do anything else). The delay is about half a second. But if I depress the Caps Lock key multiple times in a row, the delay gets strung together and becomes much longer. It's definitely a bug and I need assistance fixing this.

You can try a safe boot to clear system cache folder as a test.

Is there an expectation to fix the bug in next mac update?

There is a software update as of 8/11/2021 macOS 11.5.2

Here are the things I've done that may have jiggled the handle:

1. Stopped using the Slack app (I was suspicious of this from watching the slack helper process in Activity Monitor)
2. Rebooted
3. Still was happening
4. Rebooted again
5. No more delays when hitting the CAPS LOCK.
6. Slack app back in use, no issues there.

It appears that maybe just rebooting a couple times helped? I'll chime back in if things start again.

I'm seeing something similar. Caps Lock seems to be the main culprit where I get a pause and/or spinning color wheel. My pause can last a few seconds. At first I thought it was Slack. I've rebooted and checked Activity Monitor for a strange spike in resources but, thus far, haven't found something obvious.

macOS Big Sur 11.5.1

MacBook Pro 16-inch 2019

i9 2.4GHz

32GB RAM

AMD Radeon Pro 5300M 4GB

Having this issue as well. Just reported bug to apple.

I have a MacBook Pro (16-inch, 2019). Running macOS Big Sur version 11.5.1.

When I press the caps lock key my computer delays for a few seconds and the spinning wheel comes up. It happens every time. This is extremely irritating. Anyone find a fix yet?

It also happens to me with the caps lock and the volume up and down keys. After restart it solved but after some time it returns.

It looks like the 11.5.2 update actually fixed it as mentioned in a lot of forums!

GO UPDATE!

I did the boot to safe mode; problem went away. I then did the upgrade to 11.5.2 and allowed the regular boot to occur.

Problem is still gone; so I'm hopeful that one of these two solutions was the cure.

After restart it seems to help. Hoping the issue does not return. Thanks for your response!
