Hello, and welcome. :-)

You could try downloading and merging the REG file for the EXE item in the table of the tutorial below to restore the default associations for EXE files to hopefully fix this for you.

I did download that stuff but not sure how to "merge"? When I opened the .exe file in that, it told me that the values contained have been added but no changes to my problem (i rebooted after that as well)

You would double click on the REG file and approve to merge it.

Since it didn't help, you could try doing a system restore at boot below using a restore point dated before this happened to undo it.

It seems my restore point isn't back far enough... If I could get regedit.exe to open I could return the values I changed back to original.

Are you getting any error messages when trying to open EXE files or regedit?

As a test, see if this below to reset Microsoft recommended defaults may help.

1) Open Settings > Default apps.

2) Scroll down, and click/tap on the Reset button under Reset to the Microsoft recommended defaults.
