Well yes and no you can release them going forward under a new licence. If you obtained your copy under the old license you can use it under the old license when you obtain a new copy you have a new license agreement. Thats absolutly possible to do.
Revoking licenses is alot harder though and changing the lizens from a foss on to another is often confusing and business inapropiate. However it is legal.
Edit:
A license is for not vopyright owners not the copyright holder. The copyright holder can basically do whatever they want.
the copyright owner can do whatever they want, but they can’t really revoke a GPL license. that’s not really a thing.
and the part about

seems to me like you are implying that “use under the old license” means “run the program on my own machine”, but that’s not true, since GPL explicitly allows redistribution and modification.
under a GPL license, you effectively give up control over your software voluntarily:
The GNU General Public Licenses are a series of widely used free software licenses, or copyleft licenses, that guarantee end users the freedom to run, study, share, or modify the software.
(highlighted the relevant portion for your convenience)
this makes revoking the license effectively impossible.
you could continue development under a different license, but that gets legally tricky very quickly.
for example: all the code previously under GPL, stays under GPL. so if someone where to modify those parts of the code and redistribute it as a patch, you couldn’t legally do anything about that.
which seems to be what the OOP claims the change to a CC-BY-NC-ND forbids, apparently misunderstanding, that this new license only applies to code added to the repo since the license change, not the code from before the license change.
Thats not completly right at least under german law (and most likely also under us law).
A license is basically a contract between you and the copyright owner.
If the copyright owner changes the distribution of a piece of software to a new license you have a diffrent contract with them. So you have to hold up this new license.
If you already had a license (in this case gpl) you can use this old contract, but you can not download a new copy delete what was added since the copyright change and use that under gpl. You would have to proof that you had the gpl license before or in this case that it got relicensed to you.
