Macbook Pro locks up and then resets

I've been having this issue on my Macbook Pro (intel 13" 2020 with four thunderbolt ports) for a while, its intermittent and difficult to reproduce consistently, but it happens fairly often. When I'm watching a full screen video, viewing a fullscreen tab or pdf, or playing a game, the computer will lock up, I'll still be able to move the mouse, but I can't force quit the application, or change spaces, and it no longer scrolls or the video no longer plays, then eventually the computer logs me out and brings me back to the lock screen. This has happened with multiple tabs open, with one tab open, with the computer on charge, with it off charge, it's also happened when not in full screen, but less frequently. I updated recently to macos26 to see if it would help, but the issue is still happening, however this is the first time it actually gave me a crash report, which I have in a text file but it is too long to post or to post using additional text, so if there is a way to upload that, just let me know. I've tried resetting smc and nvram, I've gone through my startup applications which I don't have any. I've tried making sure I have enough disk space, and uninstalling programs, opening up activity monitor to see if there is anything unknown running or taking up a lot of cpu, reseting, everything I can think of, but no dice. It's difficult to troubleshoot as like I said I can't reproduce the issue at a moments notice, it just happens frequently. Any help would be appreciated. Thanks!

You can post the copy & paste crash report here in its entirety— use the menu bar Additional Txt box

Just tried that, got an error saying: "Error: Body should not exceed 250000 characters."


You have to help yourself here—


so break in two or three or a as big a chunk as it will take.....(?) Take it off the bottom.


post multiple Additional TXT boxes if it is an issue.


need something to work with here from the top down.
