Was reading an email wi5 a video by trusted source. MacBook Pro, froze and sounded like a skipping record. Then shut down, kept restarting itself. Finally got it to boot up in recovery mode. Ran disk utility fine. Restarted, got to login screen, then got in a loop of restarting. Restarted in recovery mode, ran disk utility again, the. Reinstalled Mac OS. It did this thing, then got to log in screen, aaaand back to shut down log in loop again.
MacBook Pro 13″, macOS 10.15
There would appear to be some piece of software and or extension installed that is causing the issue.
Reason for this conclusion is that Safe Boot eliminates third party software and extension from loading. That would explain by it will boot in Safe Mode but not in normal mode.
To run the below application suggest attempting in Normal Boot. But, if that does not work - boot in Safe Mode and then run the application. It will identify the install software even if it is not loading.
Etrecheck
Suggest downloading the Application Etrecheck directly from a well Respected ASC Contributor.
The application is free or paid from added features.
Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ).
It will take a Snap Shot - both the hardware and software.
The Report will Not Reveal Any Personal Information.
Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )
We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.
Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.
This includes AntiVirus, Disk Cleaners, Disk Optimizes, UnInstaller etc.
The The Built in Security is all that is required.

Thank you for the Etrecheck Report
Please refer to below as several pieces of Software maybe the Root Cause >>
MacBook Pro (16-inch, 2019)
macOS Big Sur 11.6.2 (20G314)
Q 1 - Antivirus software: Apple and ESET
A 1 - ESET would not run in Safe Boot as Safe Boot would eliminate it from loading.
Further, there are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX Foundation and Permission Limitation.
The The Built in Security is all that is required to protect the computer.
Q 2 - Launchd: ~/Library/LaunchAgents/com.synamedia.videoguardmonitor.plist
Executable: /bin/sh -c $HOME/Library/Synamedia/VideoGuardPlayer/VideoGuardMonitor/VideoGuardMonitor.bundle/Contents/Resources/launch.sh
A 2 - You can use Find Any File (FAF) do a search for "VideoGuardMonitor". Suggest running this Application from a Safe Mode.
Q 3 - No Time Machine backup - Time Machine backup not found.
A 3 - A Time Machine Backup is very useful and can be used to Revert to Previous Working macOS.
Q 4 - Unsigned files - There are unsigned software files installed that could be adware and should be reviewed.
A 4 - Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac.
It is free or paid for added features.
Run the Application and it should remove the malware / adware.
Once done, restart computer and test.
What happens with attempting a Safe Boot
Safe mode may help you resolve or isolate problems that you’re having with your Mac.
When you start up in safe mode, your Mac prevents some software, such as startup items, from loading, and it performs a check of your startup disk. Your Mac may take longer to start up because of the check.

Please review one posting before your recent reply above.
All the Instructions to possibly resolve the computer issue are listed
got it to start up in safe mode. Ran disk utility. Worked. Then turned off and restarted it, back to the restarting loop when not in safe mode. What do I do when it’s in safe mode
Here it is
Also, I have ESET security. Does that work when in safe mode? I thought maybe I’d run a check, but it said it couldn’t communicate with background. Still can’t get it to start up in regular mode.
