"Check for Updates" Button not working or updating mods from pack imported from Curseforge

[CommandBlockGuru]

• [Yes] I searched the issue tracker for other issues covering my case
• [Idk] This is a Launcher issue. (Usually if you can reproduce it with a fresh instance)

Describe the bug
Had a modpack from Curseforge with 61 mods (if that's important) on 1.19.4 that I updated to 1.20.1 on GDLauncher, all mods from Curseforge. When I attempt to update all of them to the new version and press "Check for updates", it either just turns a darker color or loads for a second and disappears, not showing anything if I try and press "Update all mods" even though most of them need to be updated.

To Reproduce
Steps to reproduce the behavior:

1. Go to Curseforge
2. Export an instance (With a lot of mods)
3. Import it to GDLauncher, wait for it to fully install
4. Update instance's version
5. Try to press "Check for updates"

Expected behavior
I expected it to see that at least most of the mods were outdated and needed to be updated, then allow me to update them to the most recent version

Possible solutions
Make it work or if it's not supposed to look at older version mods, make it do that. Idk what's wrong with it
