Mods Deactivating on Their Own in World Creation

Can’t add mods to new worlds without them self deactivating. One or two, maybe 3 mods can be added safely but then I can’t touch them. Once I rearrange their order, they all deactivate. Sometimes one or two mods can be moved before they deactivate. If the mod has settings, I can’t edit those either. A single edit will deactivate every mod once the settings menu is closed. This wasn’t a problem until 1.21.120. Have checked updates for all mods, checked compatibility, deleted mods which were out of date or no longer compatible, checked Minecraft updates, even went so far as to activate 1 mod at a time to locate offenders or see if it would still effect lone mods. Lone mods with settings still self deactivate. Past in game troubleshooting attempts, I ensured my tablet was up to date, cleared memory, cleared caches, even deleted old worlds I haven’t touched in awhile or that had mods which were now incompatible or out of date.

Normally I can rearrange 10+ mods without any issue and edit every mod with settings in the world creator just fine. All mods stayed active regardless of how many times they were moved or edited. Very frustrating when trying to create new worlds.
