Cryptomator bugs out when transferring files from Google Drive to pCloud Vault

When i copy 2GB zip files from my Google Drive folder and paste them into pCloud Vault on my file explorer, once the first file gets to 100% it freezes. It cannot finish the first file. Cryptomator sits there hogging nearly all CPU resources, at that point the computer lags, and file explorer lags extremely badly as well.

Any ideas why no files can transfer? Is there a file size limit on cryptomator?
