Perhaps try Safe mode on startup, that may find small issues

in checking your macOS & repair them. Two sets instructions

for Safe mode use; one, Intel-mac & other for new hardware.

Includes both Silicon+Intel & other details, as needed.

.Other Support articles on 'Safe boot' mode, vary.

"Start up in safe mode"

Find out whether you're using a Mac with Apple silicon, then follow the appropriate steps.

IF using a Mac with Apple silicon

1. Shut down your Mac.
2. Press and hold the power button on your Mac to turn on your Mac and load startup options. When you see the startup options window, release the power button.
3. Select your startup disk. It's named Macintosh HD, unless you changed its name.
4. Press and hold the Shift key, then click the “Continue in Safe Mode” button below your startup disk.
5. When you see the login window, you might also see “Safe Boot” in red

text in the upper-right corner of the login window. Log in to your Mac.

"You might be asked to log in again."

[If asked Restart to exit Safe mode.]

Maybe try the suggested 'Safe boot' startup restart cycle.

Not like it's never tried before, in similar circumstance.

And depending on the hardware version Mac computer

either type (Apple Silicon vs. Intel-mac) architecture will

do nicely. Success either way ~ IF you follow instructions.

Which have been spelled-out in an earlier reply above.

At least that does no harm, when done correctly; indicator

shows in Red text "Safe" in the sequence. If Not, it only will

do a regular re-start, and does not enter Safe mode.

..Either it Will work its magic if applied correctly, or it Won't..

Sound like you did good! Maybe just a simple re-start

might've been like a Mouse that scared an Elephant?

.Just the thought of mouse inside an elephant's nose!🤣

Or the 'Safe mode' can work some hidden wonders too.

Good

Mine is doing the literal exact same thing. What did you do to fix it?
